The data in the table show the number of pounds of bananas sold per week at a grocery store when the banana display was positioned in the produce, milk, and cereal sections of the store.

a) Perform a one-way ANOVA using

alphaαequals=0.05

to determine if there is a difference in the average number of pounds of bananas sold per week in these three locations.

b) If warranted, perform a multiple comparison test to determine which pairs are different using

alphaαequals=0.050

Please help, I am very confused

A commuter is accustomed to leaving his house between 7:30 and 8:00 AM, the drive to the station taking between 20 and 30 minutes. It is assumed that the departure time and length of trip are independent random variables, uniformly distributed over their respective intervals. There are two trains which he can take: the first leaves precisely at 8:05 AM and takes exactly 35 minutes for the trip, and the second leaves at 8:25 AM and takes 30 minutes. (a) Assuming that he makes one of these trains, what is his average arrival time at the destination? (b) What is the probability that he misses both trains?

An engine manufacturer has observed failures with their product. In the last 6 years, they have experienced 2 engine failures one year, 3 engine failures in two consecutive years, 4 engine failures one year, and 5 engine failures in each of the preceding two years (two in the last month, alone). The CEO of the engine manufacturer wants to reassure customers. He promises that in the next month, there will not be multiple engine failures (no more than 1 failure). Assume the probability of failure is exponential.

Question: The CEO asks you to calculate the probability that they are correct: What is the probability there will be no more than a single engine failure in the next month?

Note: Making promises to reassure customers and then asking to hear the numbers. This would never happen in the real-world, by the way.

A programming team is in the process of testing a new software module. As part of the effort, they need to estimate the success rate of the module when used with a particular operating system. To do this, they plan to run the module on a randomly selected set of computers, record how many individual runs execute properly, and use that result to calculate the sample success rate (p-hat, the number of successes divided by the total number of tests). Assuming a confidence level of 99%, calculate n, the number of computers they need to use for the test in order to ensure a 0.03 margin of error in the success rate. Calculate n for the following two cases: (1) no assumption is made about the value of the sample success rate, and (2) in a recent test of a similar software module, that module ran successfully in 94% of the tests. Round your answers upward to the next higher integer.

(1) If no assumptions are made about the sample success rate, the sample size required to ensure a margin of error of 0.03 is n = .

(2) If it is assumed that the new module will run successfully roughly in 94% of the tests, the required sample size required to ensure a margin of error of 0.03 is n =
