11. You manage a grocery, and you are wanting to see what the average customers spends per visit, and then testing whether your customers spend, on average, more than $75 per visit. You take a random sample of 50 customers and find the mean of this sample is $98. From a randomization distribution of 3000 samples, you calculate a p-value of 0.007. a) Define the parameter of interest in words (and in context), and give the correct symbol for this parameter. (4 points) b) What is the alternative hypothesis for this tests? (2 points) c) Which number in this problem is the sample statistic? Give the value and the correct notation. (2 points) d) At what value should will your randomization distribution be centered: 75, 50, 98, 3000, or 0.007? (2 points) e) If instead of carrying out a test you made a confidence interval, at what value will your bootstrap distribution be centered: 75, 50, 98, 3000, or 0.007? (2 points)
