Question 1:
Suppose that 100 tires made by a certain manutacturer lasted on the average 21,819 miles
with a standard deviation of 1,295 miles. lest the hypothesis at the 0.05 level of significance.
Ho : 4 = 22,000
Ha: 4 < 22,000
Question 2:
1. find the equation of the least squares line.2. What is the predicted value of y when 2 = 14?
