Concept #1: Determining the P-Value

Concept #2: Determining the P-Value: Intro

Practice: McDonalds needs to determine caloric values for their new lines of products. They found that a random 
sample of 225 of these new sandwiches had a mean of 480 calories with a standard deviation of 300 calories. If McDonalds 
is trying to claim that the sandwich is 450 calories, what would be the p -value of this test?

Practice: Referring to Practice 1, this same sample of sandwiches had an average protein count of 38 grams. The 
variance of the protein count was 27 grams. McDonalds want to claim that this sandwich contains at least 40 grams of 
protein. What is the p-value and what would you conclude regarding the claim made by McDonalds?

Practice: In 2000, 75% of Americans voted. You want to test to see if this has decreased. You sample  625 people and 
find that 470 people voted in the 2012 election. Test the claim that at most 75% of people voted in the 2012 election. What 
is the p-value and what can you say about your claim?
