a) Use the data to construct a 98% confidence interval for the mean number of friends. (Round to three decimal places as needed.) b) Interpret the interval you constructed in part a. Choose the correct answer below. O A. 98% of all people have a number of friends within the confidence interval. O B. There is 98% confidence that a randomly selected person will have a number of friends within the confidence interval. O C. There is 98% confidence that the true mean number of friends is within the confidence interval. O D. 98% of all samples will have a mean number of friends within the confidence interval. i Resampling c) What assumptions did you make, if any, in interpreting the interval? Select all that apply. A. It is assumed that the population is nearly normal. B. It is assumed that each bootstrap sample is nearly normal. OC. No assumptions were made. O) D. It is assumed that the individual values in the sample were independent. OE. It is assumed that the individual values in the sample were dependent.Resampling Results + 250- 200- 150- # of Samples 100- 50- 0- 720 740 760 780 800 Mean Number of Friends Summary statistics of the mean: 0.5% 1% 2% 2.5% 5% 95% 97.5% 98% 99% 99.5% 715.301 719.552 725.292 727.072 734.521 800.388 807.048 808.543 812.182 815.575
