Dr. Vegapunk thinks that watching anime (Japanese animated shows) decreases social skills in college students. To test this, Dr. Vegapunk randomly selected 30 brooklyn college students and assigned them to watch an episode of anime everyday for a week. After the week, each of the students answered a questionnaire about their social skills. The results showed that the sample had a mean social skills score of 7.3 and a standard deviation of 2.4. A previous study showed that the overall population of brooklyn college students had a mean social skills score of 6.2, but the standard deviation was not reported. Dr. Vegapunk decides to use an alpha level of 0.05.

a) what test should he use?

b) what is the alternative hypothesis?

c) what is the null hypothesis?

d) what is the critical value?

e) what is the obtained statistic?

1. A university wants to estimate the proportion of its students who smoke regularly. Suppose that this university has N = 30, 000 students in total and a SRSWOR of size n will be taken from the population. a) If the university wants the proportion estimator ˆp to achieve the precision with tolerance level e = 0.03 and risk α = 0.1. Estimate the minimal sample size needed for this estimation. (z0.1 = 1.28, z0.05 = 1.65) b) Suppose that, in a pilot study, the university takes a SRSWOR of size 20 students, among which only 2 students are found to be smokers. Based on this preliminary result, re-compute the minimal sample size for part (a). c) Suppose the university chooses the sample size estimated from (b), and finds that the sample proportion is ˆp = 0.15. Construct a 90% confidence interval for the population proportion p

C++ programming: FUNCTIONS WITH DIFFERENT RETURN TYPES AND PARAMETERS

NuMetro has a special on movies for all members of the public but special discounts for students and pensioners. If pensioners or students buy a movie ticket they receive 10% if they buy a movie and popcorns, they receive 20% discount. Other customers only receive a discount when they buy a movie ticket and popcorn; there is no discount for just a movie ticket alone. Write a program named question5b.cpp that will consist of two functions. The program must prompt the user for type of customer (‘p’ for pensioner, ‘s’ for student, ‘o’ for other). It must then call the relevant function according to that entry. The first function must receive the customer type and calculates discount for pensioners and students. The second function calculates the discount for customers that are not pensioners or students.

the scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=536.1μ=536.1 and standard deviation σ=27.9σ=27.9.

(a) What is the probability that a single student randomly chosen from all those taking the test scores 540 or higher?
ANSWER:  

For parts (b) through (d), consider a simple random sample (SRS) of 35 students who took the test.

(b) What are the mean and standard deviation of the sample mean score x¯x¯, of 35 students?
The mean of the sampling distribution for x¯x¯ is:  
The standard deviation of the sampling distribution for x¯x¯ is:

(c) What z-score corresponds to the mean score x¯x¯ of 540?
ANSWER:

(d) What is the probability that the mean score x¯x¯ of these students is 540 or higher?
