Short Answer

Expert verified

The Sum of Squares Error is 7920.4

Step by step solution

01

Given Information

Using the table, we have to find the Sum of Squares Error

02

Explanation

Data for weights of men Calculate Sum of Square Error for the above data, using the one-way ANOVA Data Analysis tool in Excel

In Excel, Click on the Menu Item Data-> Data Analysis

In Data Analysis, Click on Anova: Single Factor, enter the Input Range, Click on Grouped by Columns, and Click Ok

03

The data shown is the recorded body temperatures of 130subjects as estimated from available histograms. Traditionally we are taught that the normal human body temperature is 98.6F. This is not quite correct for everyone. Are the mean temperatures among the four groups different? Calculate 95%confidence intervals for the mean body temperature in each group and comment about the confidence intervals.

What is the Mean Square Error?

Two coworkers commute from the same building. They are interested in whether or not there is any variation in the time it takes them to drive to work. They each record their times for 20commutes. The first worker’s times have a variance of 12.1. These coworkers' times have a variance of 16.9. The first worker thinks that he is more consistent with his commute times. Test the claim at the 10% level. Assume that commute times are normally distributed. Is the claim accurate?
