Don't swap positions of lower/upper endpoints Lower endpoint: 50.684718 Upper endpoint: 59.415282 (c) Choose the options from below to fill the blanks to interpret this confidence interval: that the is between 50.68 and 59.42 seconds We are A 95% confident, true mean 8. 95%, sure, true, mean C 90%, confident, population, mean D. 95% confident, sample, mean (d) What is the value of point estimate in this confidence interval? (This question has the similar form. What is the average perceived clapsed time in this sample? What is the value of ?? They are asking about the same thing) 1 le) What is the value of margin of error in this confidence interval? If we generate a lot of samples of the same site (en = 20) and calculate the confidence intervals for the population mean from them. What percentage of these intervals will contain the true parameter? e) If we generate a lot of samples of the same size en 20 and calculate the confidence intervals for the population mean from them. What percentage of these intervals will not contain the true parameter? A Does the confidence interval calculated by JMP contain the true parameter? A Yes B. No C. We don't know
