7. A 99% confidence interval (in inches) for the mean height of a population is 65.89 <u< 67.51. This result is based on a sample of size 144. If the confidence interval 66.11<u<67.29 is obtained from the same sample data, what is the degree of confidence?
Please show work step by step. and round answers to 4 decimal places. thank you! 13-14. A 99% confidence interval (in inches) for the mean height of a population is 65.7<<67.3. This result is based on a sample of size 144. Construct the 95% confidence interval.
Assuming that the population is normally distributed, construct a 90% confidence interval for the population mean, based on the following sample size of n-6. 1, 2, 3, 4, 5, and 19 Change the number 19 to 6 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval. Find a 90% confidence interval for the population mean, using the formula or calculator.
