Use the data below to test the claim that the weight loss was greater with the low fat diet compared to the low carbohydrate diet.  Use a 10% level of significance. Low Fat Low Carbohydrate x¯1=3.7lbs 1=5.2lb n1=57 x¯1=2.7 lbs1=4.9lb n1=62   Identify the tail of the test.       What is the P-value?        Will the null hypothesis be rejected?        Is the initial claim supported?

In the population of senior students at Shermer High School, the proportion who plan to attend college is 0.64.
