Your team’s coach has hypothesized that average number of points scored by your team in the team’s years is less than 110 points. For this test, you assumed that the population standard deviation for points scored is unknown. You tested the claim using a 1% level of significance. Explain the steps you took to test this problem and interpret your results. What is the Null Hypothesis (statistical notation and its description in words)? What is the Alternative Hypothesis (statistical notation and its description in words)?
