Hi everyone, I just need help understanding how I got the wrong answer on a practice test. Here is the prompt:

"A teacher wants to determine if the pass rate for a particular group of students is significantly different from 81**%.**

What is the minimum sample size needed in order to perform a hypothesis test for proportions?"

The answer I got was 13.

I used the equation n(p) is greater than/equal to 10.

But the correct answer is 53, which I know can be solved by using n(1-p) is greater than or equal to 10.

My issue is the question asked for minimum sample size, so wouldn't that mean 13 is the minimum? I am doing an online course, and the online instructor just repeated n(1-p) to me via email without explaining why that is preferred over the one I used. Can anyone help?

I’m so frustrated living in America because fuck it if you’re poor.

Husband and I are first time parents to an 8 month old. LO got sick and developed a 100.9 fever with shallow breathing. We called the night nurse, who recommended we go to urgent care or the ER. This was at like 9 pm so our only choice was the ER. 3 hours later, he just has a summer cold and was given Motrin for the fever. But get this: the copay for our visit was… $250!!!! And I pay almost $1000 a month for insurance to cover my family. What the actual fuck?! we are in so much debt because I didn’t have paid maternity leave, and I had complications from an emergency c-section. I just hate that money problems keep piling up. Was I supposed to ignore what the night nurse said? I was scared for my child! But here’s a bill that could’ve covered groceries for the month! Fuck!!! I’m so mad. I feel like I’m never going to get out of this hole we’re in.

I hate having to choose between my child’s health and money. Like that was not an insignificant amount. Of course I always want to be safe, but now we’re both safe and sorry.

/edit. Guys it’s not written on my insurance card what the copay is for an ER visit. I also feel stupid enough for not having called ahead of time. Tbh I went to the ER multiple times during pregnancy and I had no copay, so i (maybe stupidly) thought it’d be similar. My point though is that I shouldn’t have to choose between money and my child. It’s frustrating. I’m frustrated. Please don’t make me feel stupid by saying stuff like “it’s not a secret” when talking about copays.

Hi, long time strokes enjoyer but first time concert goer. I have NEVER been to a live show by any band before, so I’m kind of getting anxious about how to plan my outing.

Hubby and I will be going to see the strokes in Minneapolis. They’re playing last Sunday night at 9:30-10:30. Do these festivals tend to run late? Is it realistic to expect them to start and end on time? They were on time for Coachella but figured it’s a more famous and therefore tightly run festival. What has your experience been in other festivals or strokes-only shows?

Also would it be weird if I bring a folding chair lol. We plan on going super early to get close to the stage, but I realize I might look completely out of place with a chair.

I’m a FTM to an 8 mo boy. Lately, I’ve been at a loss for what to do to entertain my fussy baby. We go on walks. We play. I try to help him practice crawling and guided walking. But that still leaves so many hours of down time. He only naps 30 mins twice a day. I’m also trying not to go out to the store to save money as we are in a bit of a financial bind. After a while, he starts getting bored and fusses. I’ve resorted to putting on a Ms. Rachel episode or 2 to entertain him. He’s happy.

But I feel so guilty. This much TV everyday can’t be good right? We don’t allow him any cell phone or tablets. Just TV. I would say he gets between 30 mins to an hour of tv per day. Maybe when he’s able to move and talk more it’ll be easier to entertain without TV? Idk

I’m a FTM to an 8 mo. I stopped breastfeeding when LO was 7.5 months. I miss it terribly. The sad thing is, he hasn’t fed from my boob since Mother’s Day, and I’m crying because I’m starting to forget what it felt like. (I EP’ed after Mother’s Day because he kept rejecting the breast)

When I was pregnant, I told myself formula or breastfeed or combo would be great. Whichever helps me and the baby! So why was my actual reaction so attached to nursing once baby came? Why am I looking longingly at posts here, missing for those days when I had clogged ducts? Anyone else feel like this? I sometimes pinch my nipple to see if there’s still milk. The amount is dwindling every day, and I’m starting to think I should re-lactate while I still can. Husband thinks this is unhealthy. Idk I’m just so distraught and unable to move on.

You’ve seen loose vs lose.

Could’ve vs “could of”

But have you ever seen… discreet vs discrete? For some reason I’m seeing it *everywhere*. Offline and online.

It just irks me a little bit, especially when I see supposedly well educated people make that mistake.

(FYI discreet = you know how to keep a secret/be subtle vs discrete = separate or distinct, e.g. discrete values in a distribution)

Bonus points if you’re also tired of seeing people use “weary” when they really mean wary or leery.

Hi everyone. I am 7 months (and a few weeks postpartum). As I write this, I can feel my breasts deflate and hang limp now that the last of the milk is being reabsorbed by my body.

Before I gave birth, I wanted to breastfeed for a year. I stopped at this point because my supply was dipping down to 1 oz per pump session despite my best efforts (and believe me, I tried EVERYTHING this community and different LC's have recommended). I no longer found the energy, time, and effort spent on pumping worth it. My baby will now switch completely to formula.

I want to cry. Scream. Throw something at the wall. When I was pregnant, I never knew what exclusively pumping was (or that it was an option), and a part of me is grieving the breastfeeding journey I never had.

I feel like a failure, but I know that's not rational or logical. I know I should be grateful I was able to give my baby what I could and that he's a very happy, healthy little munchkin. At the same time, I feel relief. I'm so glad my body can be mine again, and I no longer have to pump at home and at work. I can get a full night's sleep (so long as baby does). There is just a mixed bag of emotions swirling in me right now.

Goodbye spectra. You were my worst enemy and best friend through the hardest thing I've ever had to do.

I’m a FTM and almost 7 months postpartum. I still think about my traumatic emergency c-section. I lost a lot of blood during the operation due to tears that occurred to my uterus and the “anatomical abnormalities”with my body. I can’t help but fixate on the fact that I would’ve died if modern medicine didn’t exist. I would’ve been naturally selected out. Like, I don’t deserve to survive, you know? Women who give birth vaginally won the Darwin awards, whereas women like me aren’t meant to reproduce and keep going. I know I know I shouldn’t think this way. I love my baby and my husband, but I keep thinking I don’t deserve this life. I know I should talk to someone.

I’m a FTM to a 6.5 month old. Since he was 3 months I struggled with nursing him since I was an undersupplier. I power pumped to get my supply up, but then at 4 months my supply regulated and I became an undersupplier again. Baby refused the boob. Became an exclusive pumper.

Everything was stressing me out. I decided to wean. Well I dropped a pump every 3 hours during the day. But have kept all my night pumps (once at 5 pm, 8 pm, and then 11 pm). I’m back to making a modest 2 oz per session. My boobs no longer hurt for skipping day pumps. Baby is happy with the milk I produce at night. Well, why not just keep at it with this new schedule?

For a long time, I thought breastfeeding and pumping had these hard and fast rules. For a lot of it, yes the rules are hard and fast. But if you’re not ready to wean, there are alternatives. So far night pumping is working out for us, and I feel great knowing I can give my baby some breast milk (in addition to formula).
