Affiliate Marketing Secrets

Please could you show how to work these two questions. I’m not sure if there is some information that was left out in question 5. Thanks in advance. =)
Question 4
A large multibranch bank is affiliated with both MasterCard and Visa Credit cards. A random sample of 50 MasterCard clients founds that their average month end credit card balance was N$944.00; for a random sample of 66 Visa card clients, their average month end credit card balance was found to be N$827.00.
Assume the population of month end credit cards balances for the clients is normally distributed with population standard deviation of N$294.00 for MasterCard and N$ 336.00 for Visa Credit cards respectively. Is there a difference in the variances between the MasterCard and Visa Credit cards clients at 5% level of significance? [12]
Question 5
In a sample 1383 Unam hostel students 979 students were found to favour to study over the weekend to improve their academic performance.
(a) Find a point estimate for the population proportion р of those in favour of studying over the weekend to improve their academic performance and interpret it. [4]
(b) Find the minimum sample size needed to estimate the population proportion at the 99% confidence level in order to ensure that the estimate is accurate within 4% of the population proportion. [5]

How can I say this without someone on here telling me I spamming affilate links on here. I’m only asking if anyone needs an account. NO AFFILIATE LINKS WHAT SO EVER HERE.

So i’m 16 and just started worrying about wrinkles.
For some reason, I’m so horribly scared
You wouldn’t believe how scared I truly am!
So first i’ll take you through my skincare routine.
Everyday, i:
cleanse
tone
If i’m staying home i put moisturizer on, Sometimes I put coconut oil on or other oils like rosehip but if i’m going out I put sunscreen on, depending on the weather in summer 30+ in winter 15+
and for going out I also apply modelsprefer BB cream for extra protection because I don’t wear make-up.
I come home that night and I do this twice a day I will,
cleanse
tone
add a moisturizer and anti wrinkle eye cream.
I only do a facial once a month, Sometimes twice.
I only exfoliate 1-2 times a week but never day’s after each other.
I ONLY drink water, I hate coffee and tea,
and soft drink is a rare for me.
I don’t smoke, I eat strawberries and blue berries every day and just started eating walnuts too.
And I take vitamin pills,
Omega 3 and vitamin e.
So why am I so worried about wrinkles what can I do to tell myself i’m doing something right or am I doing something wrong?

I don’t know my pattern password or google account. How can I get back into my phone?

Blue, Yellow, Red, Orange or Green ?
