A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.10 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute?Times (in seconds): 76, 90, 47, 71, 54, 30, 69, 75, 74, 55, 76, 79, 101, 101, 77**Hypothesis Test:**Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?- **Option A:** $ H_0: \mu = 60 $ seconds $ H_1: \mu > 60 $ seconds - **Option B:** $ H_0: \mu \neq 60 $ seconds $ H_1: \mu = 60 $ seconds - **Option C (Correct):** $ H_0: \mu = 60 $ seconds $ H_1: \mu \neq 60 $ seconds - **Option D:** $ H_0: \mu = 60 $ seconds $ H_1: \mu < 60 $ seconds **Determine the test statistic:**(Round to two decimal places as needed.)

Solution To test the mean we will use t distribution for single mean.

Students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Assume that a simple random sample has been selected.

Identify the null and alternative hypotheses. Identify the significance level for this test? P-value? If the P-value is less than or equal to the significance level, reject the null hypothesis Ho. Otherwise, fail to reject Ho. State a final conclusion that addresses the original claim. Based on the results, decide whether it appears that students are reasonably good at estimating one minute.
The coach of a very popular men’s basketball team claims that the average distance the fans travel to the campus to watch a game is 35 miles. The team members feel otherwise. A sample of 16 fans who travel to games was randomly selected and yielded a mean of M= 36 miles and s= 5 miles. Test the coach’s claim at the 5% (.05) level of significance. one-tailed or two-tailed test: State the hypotheses: df= tα or t value for the critical region = sM = t (test statistic)= Decision:
A college alumni Organization sent a survey to all recent graduates to ask their annual income. 20% of the alumni responded, and their mean annual income was $40,000 with a standard deviation of $10,000. Explain why these data should not be used to construct a confidence interval for the mean annual income of all recent graduates.
