The Random Variable X: 3. Data will be collected from a normal distribution (population) with a mean of =80 and =2.5. If our sample size for our study will be = 20, determine the following: 3c. Determine the value k, so that P(X k)=.01 (4-decimal places). Confidence Intervals: 4. Data is collected from a normal distribution. Our data summary is: X=121.5, s = 2.4, and n = 20. 4a. Determine a 95% confidence interval for the population mean (). Enter the left number in Top Hat. 4b. Determine a 95% confidence interval for the population standard deviation (). Enter the left number in Top Hat.
