This week I decided to study a population mean. I believe the population mean number of times that people bring lunch to work in a week is 2.5. I asked 15 people how many times they bring lunch vs buy lunch in a week and got the following information: 3 4 3 2 5 5 2 4 2 1 4 3 5 4 3

My Hypotheses are:

H0 : μ = 2.5

HA : μ ≠ 2.5

At the α = .05 level:

Calculate p-value.

Calculate t-stat.

Write a hypothesis test problem using the problem below. You believe that the population mean number of times that adults go to the gym each week is less than 2.5. You spoke with 10 people and found that they went to the gym 2, 3, 5, 3, 0, 1, 7, 3, 0, and 3 times last week. You then would choose to test this hypothesis at the .05 significance level. Assume a random sample.

Last week I compared 6 compound bows, this week I want to see if the mean price for a compound bow is less than the mean price of a crossbow. I looked at 6 manufacturers of compound bows with prices of, 1,100, 1,000, 1,149, 999, 1100, 999. I looked at 6 different crossbow manufacturers and they were priced, 949, 1,399, 1,499, 1,099, 999, 1,019. Test with a 0.05 significance level.
