Very few of you attempted this fun problem! However, those few that did really hit the target! Congratulations to all of you that attempted this case study!   The Life Insurance Case Study from Week 3 utilized the Z-score for Normal Distribution (Continuous Probability). (AKA Continuous Probability which is the Probability of AN event occurring).     Let me walk you through this problem, step by step.   The problem gives us 3 numbers   The Mean/Average for this data set is 60% The data point of interest (X) is 64% (640 homes out of a sample of 1,000) - We are interested in understanding if At Least 64% of the homes (out of 1,000) purchased a Life Insurance Policy in the last year N = 1,000   Find the Standard Standard deviation of the Proportion. This is our 1st step because it is not provided   = .0155 The Standard Deviation of the Sample Population is .0155 FInd the Z-score X = .64 U = .60 O = .0155 .64 - .60/.0155 = Z Z = 2.58   The 4th step is to find the Area of the Curve…

It is assumed that the distribution for the length of time they last is approximately normal. Researchers in a hospital used the drug on a random sample of 9 patients. The effective period of the tranquilizer for each patient (in hours) was as follows: 2.6; 2.8; 3.0; 2.3; 2.3; 2.2; 2.8; 2.1; and 2.4. Construct a 95% confidence interval for the population mean length of time. (i) State the confidence interval (Round your answer to two decimal places.) (ii) Calculate the error bound. (Round your answer to two decimal places.)
