I am new to statistics, I have the Megastat, but I don't think I am using it correctly. Any help would be greatly appreciated.

The production manager at Bellevue Steele, a wheelchair manufacturer, want to compare the number of defective wheelchairs produced on the day shift with the number on the afternoon shift. A sample of the production from 6 day shifts and 8 afternoon shifts revealed the following defects.

Day 5,8,7,6,9,7

Afternoon 8,10,7,11,9,12,14,9

at the .05 significance level, is there a difference in the mean number of defects per shift?

a. State the null hypothesis and the alternate

b. what is the decision rule

d. what is the decision regarding the null hypothesis

e. what is the p-value

f. interpret the results
