Listed in the ac table are sample times econds) that animated hildren's vies showed the use of tobacco. The bootstrap method is planned to be used to construct a 90% confidence interval estimate of the populatio mean μ. For this sample data, what is a bootstrap sample? 0, 0, 74, 51, 0, 0, 0, 17, 165, 0, 37, 6, 11, 2, 0 Choose the correct answer below. O A. More than 15 of the times in the provided sample, selected randomly with replacement OB. 15 sample means, each generated by randomly selecting a fixed number of the times in the provided sample without replacement and finding the mean of those times O C. 15 sample means, each generated by randomly selecting a fixed number of the times in the provided sample with replacement and finding the mean of those times OD. Less than 15 of the times in the provided sample, selected randomly with replacement OE. Less than 15 of the times in the provided sample, selected randomly without replacement OF. 15 of the times in the provided sample, selected randomly with replacement

A random sample of 13 health maintenance organizations (HMOS) was selected. For each HMO, the co-payment (in dollars) for a doctor's office visit was recorded. The results are as follows. 9, 11, 6, 10, 6, 12, 11, 11, 7, 10, 6, 9, 10 Send data to calculator Send data to Excel Under the assumption that co-payment amounts are normally distributed, find a 99% confidence interval for the mean co-payment amount in dollars. Then find the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: || Upper limit:

Dr. Higney, an academic researcher in an English department, wants to learn about the average length of a novel. In order to do this, Dr. Higney collects data on the word counts of 200 randomly selected novels. The sample mean of this data set is = 85252 with a sample standard deviation of 8413 words. Using this data, construct a 90% confidence interval for the true mean length of novels. (84,273.50, 86,230.51) (82719.67,89784.33) (94086.04, 96417.96) (80937.53, 90566.47) S

A medical study followed a sample of 14 heart patients who had received electronic pacemakers.  The time (in months) to the first electrical malfunction was recorded as follows: 23,  14,    20,    16,    22,    14,    12,    8,   12,      24,    14,     10,  20, 16 Find the 95% confidence interval for the population mean. Please type only the upper interval with three decimal places. For example if CI= ( 10.25, 15), you type 15 as your answer.
