(what is it?).

Jack has saved $225 at the end of every month in his bank account for 6 years with the rate of interest being 3.6% p.a. compounding monthly, then he decided to go to school for 5 years when he could not contribute to his account. After his studies ended (at the end of the 5th year at school), he moved his balance to another account and started to withdraw equal amounts of money from his account at the end of every quarter for 10 years. Find the size of his quarterly withdrawals if interest has been 4% p.a. compounding quarterly.

The mean population IQ is 100 with a standard deviation of 15. A principal at a certain school claims that the mean IQ score of their students in his school is greater that 100. A random sample of 30 students IQ scores have a mean score of 112. Significance level α = 0.01
(a) State the null and alternate hypotheses
(b) Calculate the z statistic value 6
(c) Determine the p value. Sketch the graph
(d) Make a decision. Reject or fail to reject H0 ?
(e) Is there sufficient evidence at the 1% significance level to support the principal’s claim? Explain your answer in relation to this context.

A recent national survey found that high school students watched an average (mean) of 7.2 DVDs per month with a population standard deviation of 0.90 hour. The distribution of DVDs watched per month follows the normal distribution. A random sample of 35 college students revealed that the mean number of DVDs watched last month was 6.20. At the 0.05 significance level, can we conclude that college students watch fewer DVDs a month than high school students? |
| e. | What is the p-value? (Round your answer to 4 decimal places.) |
