A 95% confidence interval obtained from a sample of 100 outpatients for the true population mean normal mean systolic blood pressure is given by (114 mmHG, 120 mmHG).
A) Find 99% Confidence Interval
B) Can you tell how much would it be wider compare to 95% Confidence Interval?
Mention all the steps for the both answers.

Suppose you are given a sample of 18 systolic blood pressures having a mean of 121 mmHg and a sample standard deviation of 10 mmHg. You need to construct a 95% confidence interval around the true population mean systolic blood pressure. What would be the critical value you would use for this confidence interval? Select one: a. 2.086 b. 1.960 c. 2.101 d. 1.740 e. 2.110
