In fact AARP claims the average annual expenditure for Americans age 50+ on restaurant food in 2008 was $1960. Suppose a 2015 study randomly sampled 42 Americans age 50+ and found an average annual expenditure on restaurant food of $2145 with a standard deviation of $600. Is there reason to believe that the average annual expenditure for Americans age 50+ on restaurant...

Suppose we are dealing with the null hypothesis that the average food expenditure of all families in Atlanta is 20 dollars a day. To test the hypothesis we collect a sample of n = 100. We get the sample mean of 22 and the sample variance of 25. Write down the value of t-statistics and corresponding p-value. Will you reject the null? Explain. Only yes or no answer will not be accepted.
