Round to two decimal places as needed.)Which proportion of a normal distribution is located bwteen z = --1.75 and z = +1.75?An investigator polls a representative sample of common cold sufferers, asking them to estimate the number of hours of physical discomfort caused by their most recent cold. Their estimates approximate a normal curve with a mean of 91 hours and a standard deviation of 23 hours. Show your z-score and p-value calculations. Inverse Normal Distribution: What is the estimated number of hours for the shortest-suffering 20 percent?
