Before conducting any statistical tests on her data, a hydrologist wanted to determine whether the data were skewed. She determined that the mean of the data was 38.75 m/s, the median was 40.42 m/s and the standard deviation was 2.75 m/s. Using Pearson’s index of skewness, he concluded:

A. the data were significantly skewed in the negative direction

B. the data were not significantly skewed in the negative direction

C. the data were significantly skewed in the positive direction

D. the data were not significantly skewed in the positive direction

E. she really didn’t know

Expert Solution

Here, we have to use the Karl Pearson's Coefficient of Skewness, Sk to answer the given question.

The detailed procedure to answer the given question is as given in the image below:-

Hence, Option A. is the correct alternative.

This answers your question.

Ahmad was conducting some tests to determine if there was a relationship between taking sleeping pills and the amount of sleep a person gets. His null hypothesis was that taking sleeping pills did not have any effect on the amount of sleep a person receives. Ahmad's alternate hypothesis was that taking sleeping pills increases the amount of sleep a person will get. If Ahmad completed his study, which of the following statements would indicate a Type II error? Ahmad's results...
