Question 4 (10 total marks; 2 marks each) Starbucks wants to compare the average amount of time people spent drinking coffee indoors versus outdoors as part of their market research. A random sample of 25 outdoor coffee drinkers spent an average of 14.6 minutes drinking coffee with a sample standard deviation of 5.8 minutes. A random sample of 27 indoor coffee drinkers spent an average of 11.5 minutes drinking coffee with a sample standard deviation of 4.9 minutes. Perform a hypothesis test using $\alpha$ = 0.05 to determine if the average time people spent drinking coffee outdoors is more than the average time people spent drinking coffee indoors. a. State the hypotheses. b. Find the test statistic (round to 4 decimals) c. Use the critical value method to test the hypothesis. d. Use the p-value method to test the hypothesis. e. Is there sufficient evidence to support the claim? State your conclusion in the context of the problem.

Problem 2. A copper cube with a side length of 250mm is sliding down an incline on a 10mu m thick film of oil. The angle of inclination is alpha =15deg . Given that the density of copper ( ho _(copper ))=(8.96(g)/(c)m^(3)) and the dynamic viscosity of the oil (mu _(oil ))=(7mPa*s), what is the terminal velocity of the copper block once the sliding motion has reached steady state?
