Question

An ice cream company owns two plants, namely A and B, and wants to test using a 5% significance level whether there is a difference in the production activities carried out in each plant in terms of mean kilos of ice cream produced per hour. Using a random sample of 35 paired observations, the sample means are 60 kilos for plant A and 75 kilos per hour for plant B. In which of the following scenarios can you reject the null hypothesis? a the sample standard deviation of the difference is 55 b the sample standard deviation of the difference is 75 c the sample standard deviation of the difference is 20 d the sample standard deviation of the difference is 45 e the sample standard deviation of the difference is 100
