- Starbucks wants to check how they are doing on their drive-thru pick up times. The franchise owner has determined that drive thru pick up times should not exceed 4 minutes. He randomly selects 50 customers to see if the pick-up time exceeds the 4 minute window. Suppose the P-value for the test was found to be 0.018. State the correct conclusion. [ Options for the answer in image. Thank you! <3](07.04 LC) Mellie is conducting a test on mold spores on bread. She uses 6 slices of bread to compare two strains of mold. She applies one strain to the left side of the bread and one strain to the right side. She flips a coin to decide which strain goes on the right side of the bread. The mold spores that appear on each side are counted and she records them in a table. Bread Number of Spots for Strain 1 Number of Spots for Strain 2 1 30 19 2 21 17 3 15 15 4 13 12 5 6 9. 6 8 4 If Mellie is to perform an appropriate t-test to determine if there is a mean difference between the number of spots per piece of bread produced by the two strains, how many degrees of freedom should she use? 4 10 12 5Jerry is considering opening a new ice cream store at a certain location on State Street in Madison. Jerry conducts some analysis and determines that a given location is acceptable only if the number of pedestrians passing the potential location averages more than 100 per hour. To check if this location is acceptable, Jerry records the number of pedestrians observed for each of 40 hours. Jerry finds that the average number of pedestrians that pass the potential location during each of the 40 hours he was observing, is 105.7 per hour. Jerry assumes that he knows the population standard deviation to be 16. Can Jerry conclude at the 1% significance level that the potential location for the ice cream store is acceptable? a. What is the correct set of hypotheses? Answer: Ho: u = 100 and H1: u> 100 v b. Determine the p-value Answer: 0.0122 c. Interpret the results Answer: There is not enough evidence d.
