8.1.1 Question Help Assuming the population of interest is approximately normally distributed, construct a 95% confidence interval estimate for the population mean given the values below. x=16.9 3= 4.3 n=12 The 95% confidence interval for the population mean is from to (Round to two decimal places as needed. Use ascending order.)
Assuming that the population is normally distributed, construct a 95 % confidence interval for the population mean, based on the following sample size of n=8. 1, 2, 3, 4, 5, 6, 7 , and 19 In the given data, replace the value 19 with 8 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95% confidence interval for the population mean, using...

If X-bar= 95, S = 22, and n = 64, and assuming that the population is normally distributed: a. Construct a 99% confidence interval for the population mean, μ. b. Based on your answer to part (a), test the null hypothesis that the population mean μ = 101 vs. the alternative that μ ≠ 101. c. What is the probability that μ = 101? d. What is the probability that μ > 101?
