A scientist took a random sample of 30 1 LB packages of ground turkey and subjected half of them to irradiation method 1 and the other half to irradiation method 2. The bacteria count was measured and sample statistics were calculated (standard deviations were 4 and 2 respectively) were calculated. (Note: Less bacteria would be better) What would be the most appropriate test to see if method 1 is better? My parameter of interest here would be: The direction of test would be:

Step 1
First, we need to identify the type of data we have. Since we are comparing two different methods of irradiation on the same type of product (ground turkey), we have two independent samples. Show more…

When performing a hypothesis test on two populations (using a two-sided test), what sample size should be used to ensure that ?=0.01 if the true difference in means is 0.07, given that ?1=?2=0.075? Assume equal sample sizes for your two populations and an significance level of 0.05. 12 27 43 60 Please show details and steps.

Flu cases this past flu season in the LRSD (n=500) were 15 per week. For the entire state, the weekly average was 16 and the standard deviation was 15.1. Are the kids in Little Rock as sick as the kids throughout the state? Test the hypothesis of no difference, and use an alpha of 0.05. How would I answer this using the five-step model for hypothesis testing? How do I know which sampling distribution to use?

Consider a hypothesis test of the difference of means for two independent populations x1 and x2. Suppose that both sample sizes are greater than 30 and that you know ĂŹĆ’1 but not ĂŹĆ’2. Is it standard practice to use the normal distribution or a Student's t distribution?
