This problem uses StatCrunch.

A local greenhouse sells coffee-tree saplings. They price their saplings based on the height of the plant. They have two workers, Susan and Karen, who measure the saplings for pricing. The greenhouse manager wants to determine if there is a significant difference in the measurements made by these two individuals. She has them measure the same set of 15 saplings. Assume that the differences are calculated as Susan – Karen.

Use this information to answer questions 5, 6, and 7.

The resulting measurements (in cm) have been saved in StatCrunch. Use the data to compute the test statistic for the difference between Susan and Karen. For help using StatCrunch for a Paired Difference T-Test click here. Give your answer to four decimal places.

Expert Solution

Let us denote the difference

d = Susan's measurement - Karen's measurement

Conclusion : There is not sufficient evidence to support the claim that there is a significant difference in the measurements made by these two individuals.
