Question

10. A normal distribution Z(, () has population mean (=100 and standard deviation (=10. Find an interval for which 95% of the data is about the mean (confidence interval about the mean, n=1) and use this interval to determine whether 85 is unusually low value or not, explain your reasoning. (Emp. Rule)

Step 1

For a normal distribution, the empirical rule states that approximately 68% of the data falls within 1 standard deviation of the mean, 95% falls within 2 standard deviations, and 99.7% falls within 3 standard deviations. Given that the population mean is 180 and Show more…

A normal distribution Z(oint ,l) has population mean oint =180 and standard deviation oint =10. Find an interval for which 95% of the data is about the mean (confidence interval about the mean, n=1 ) and use this interval to determine whether 85 is unusually low value or not, explain your reasoning.
