Question

Exercises 17–20 are based on data sets included in Appendix B. The complete data sets can be found at www.TriolaStats.com

In Exercises 5–20, conduct the hypothesis test and provide the test statistic and the P-value and/or critical value, and state the conclusion.

Last Digits of Weights Data Set 1 “Body Data” in Appendix B includes weights (kg) of 300 subjects. Use a 0.05 significance level to test the claim that the sample is from a population of weights in which the last digits do not occur with the same frequency. When people report their weights instead of being measured, they tend to round so that the last digits do not occur with the same frequency. Do the results suggest that the weights were reported?
