Problem 6-72

. It is possible to obtain a quick and dirty estimate of the mean of a normal distribution from the fiftieth percentile value on a normal probability plot. Provide an argument why this is so. It is also possible to obtain an estimate of the standard deviation of a normal distribution by subtracting the sixty-fourth percentile value from the fiftieth percentile value. Provide an argument why this is so.

Step-by-Step Solution:
Step 1 of 3

Test Statistic  measures how far the sample data diverge from what we would expect should the null hypothesis be true  So, a test statistic with a high magnitude would show that the date is not consistent with H o P-values  the probability (when H0 I true) that the test statistic takes a value that is as extreme or more extreme than what is observed  A small p value means stronger evidence against Ho provided by the data, and you reject the null hypothesis Significance levels  Denoted by  Used as evidence for or against H 0  If a p value is smaller than , we reject H o  If the p value is larger that , we fail to rejectoH  If a significance level is not given, always assume = .05
