K question In a random sample of eight cell phones, the mean full retail price was $431.00 and the standard deviation was $162.00. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 90% confidence interval for the population mean u. Interpret the results. Student's t-Distribution Table Identify the margin of error. (Round to one decimal place as needed.) Construct a 90% confidence interval for the population mean. (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.) O A. With % confidence, it can be said that the population mean full retail price of cell phones (in dollars) is between the interval's endpoints. OB. It can be said that % of the population of cell phones have full retail prices (in dollars) that are between the interval's endpoints. O C. % of all random samples of eight…

Bones Brothers & Associates prepare individual tax returns. Over prior years, Bones Brothers has maintained careful records regarding the time to prepare a return. The mean time to prepare a return is 90 minutes, and the population standard deviation of this distribution is 16 minutes. Suppose 100 returns from this year are selected and analyzed regarding the preparation time. What is the probability that the mean time for the sample of 100 returns is between 88 minutes and 92 minutes? Multiple Choice Approximately 1 0.1956 0.7752 0.7888
