Q: Previous study conducted at the Texas State University reported that first year college students spent 5 hours per week, on average, speaking phone. The students statistics club assumes that, currently, the mean is higher. 125 randomly chosen first-year college students were asked how many hours per week they spend talking by phone. The sample mean was 5.94 hours with a sample standard deviation of 6.37 hours.
a. What is the population parameter to test?
b. What is the sample statistic provided?
c. What are the null and alternative hypotheses for this test?
d. Perform the test.
e. Find the p-value of the test (the table is provided)
f. Mark the graph below and show all components of the test ((t's a blank continuous bell shaped curve)
g. Make your decision
h. State your conclusion in terms of the problem.

QUESTION 2 Previously, an organization reported that teenagers spent 4.5 hours per week, on average, on the phone. The organization thinks that, currently, the mean is higher. Fifteen randomly chosen teenagers were asked how many hours per week they spend on the phone. The sample mean was 4.75 hours with a sample standard deviation of 2 hours. Assume that hours per week they spend on the phone are normally distributed. At a significance level of 5%, test the claim of...

The president of a university claims that the mean time spent partying by all students at this university is not more than 7 hours per week. A random sample of 40 students taken from this university showed that they spent an average of 7.5 hours partying the previous week with a sample standard deviation of 2.3 hours. Use the p-value approach to test at a 5% significance level whether the president’s claim is true.
