Answer #1

Solution Let the population mean for Sandwich is mu1 and pollution mean for pizza/pass is mu2

Then to test the hypothesis

H0: mu1=mu2 vs.

Ha: mu1 is not equal to mu2

Then using Anova for testing the means of two groups below:

conclusions: on the basis of pvalue. Our result is not significant therefore we reject the null hypothesis that is there is no difference between the means od sandwich ans pizza/pasta.
