- You want to know if men or women sleep the same number of hours on average. You select a representative sample of 50 men and 50 women and find that the average hours of sleep per night for men and women were 7.1 hours (s = 0.9) and 6.9 hours (s = 0.9), respectively. a)State your hypotheses
b) Calculate the test statistic. Round your answer to 2 decimal places.
c)Find the p-value. Round your answer to 4 decimal places. Interpret the result in context.
d) Do you reject or fail to reject the null hypothesis at a 95% confidence level? Interpret the result in context.
e) Calculate a 95% confidence interval for the average number of hours men sleep per night. Round your answers to 3 decimal places. Interpret it in context.
f) Calculate a 95% confidence interval for the average number of hours women sleep at night. Round your answers to 3 decimal places. Interpret it in context.
g) You calculated a 95% confidence interval to estimate the true average number of hours that men sleep at night and another 95% confidence interval to estimate the average for women. If the two intervals overlapped with each other, would you be able to say that the average number of hours that men sleep per night is statistically different at the .05 level from the average number of hours that women sleep at night? Explain your reasoning.
