a. Test the claim that the contents of cans of diet soda have weights with a mean that is less than the mean for the regular soda.

  1. i) What are the null alternative hypothesis?

 

  1. ii) What's the test statics?

 

iii) What's the P-value?

 

  1. iv) State the conclusion

 

  1. vi) construct a confidence interval suitable suitable for testing the claim that the two samples are from populations with the same mean

 

vii) Does the confidence interval support the conclusion found with the hypothesis test?
