Practice Hypothesis Testing for Two Population Parameters For each question, answer any sub questions and complete parts (a) - (d) when asked to perform a hypothesis test:

1. Identify the claim in symbolic notation and the hypotheses to test.

(b) Find the P-value.

(c) Make a conclusion on the null hypothesis.

(d) Make a conclusion on the original claim.

(4) Use a 0.01 significance level to test the claim that the mean amount, in dollars, spent by an American on groceries for food is greater in 2017 than it was in 2007. A simple random sample from 2007 of 1,235 Americans found a mean amount of $2,485 spent annually on groceries for food and a standard deviation of $88. A simple random sample from 2017 of 2,310 Americans found a mean amount of $4,300 spent annually on groceries for food and a standard deviation of $103.
