Please Help. I Don’t Know Which Method To Use. Homework. University Level Please?


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]

I Need Help Deciding Which College To Go To. Help?


Right now I’m deciding between two colleges and I really can’t choose. They are both colleges in the same city.
College A is a public school that I always had my sights set on before I found the other one. It is a huge school, with huge class sizes. It is the cheaper of the two. I like the amount of clubs and orgs on campus, but I’m not sure i want to be a nameless face in a crowd in classes. It has a highly ranked program for my selected major and has many great options I can choose from if I choose a different one. I already have friends here so I have connections for a social life. However when I visited, Im not sure i loved the campus vibe. I could probably find my niche, but I think it would be harder.
College B is a medium-small private school that is more expensive, about double the amount of loans, but they gave me a scholarship. It has a lot of wealthy students so I don’t know if I would feel out of place in that regard. Major wise, it has my major Computer Science, but it is only a BA and is not a very big one since the school is primarily a business school. They also don’t have as good of a selections of majors that I can choose from. I like that it has small class sizes, because i feel like the teachers are more enthusiastic about teaching and i can make friends in classes more easily.
I don’t know anyone at this school so I would be alone, but I feel like the school is lively, the campus is much more beautiful, and has a lot of athletic students like me. However, a lot of people at this school like to party, and im not a partier really. I’m more of a stay-in type and I’m afraid my friends would not like that about me here where at school A most students are like that.
I bet I could see my friends at the other school sometimes because its only 10 minutes away. But is this school worth the price and not as good of major program?

B) Organisms, known as autotrophs, that synthesize their own food source (glucose) by using the process of photosynthesis.
C) All of the living populations that are found and interact within an ecosystem.
D) Complex interconnections that show the feeding relationships of organisms with an ecosystem. The more connections, the more stable the ecosystem.
E) The non living factors that influence living organisms such as water, temperature, soil, and atmosphere.
