A teaching professional believes that the average gain is not $2,200. Complete parts a through c below. a. In order to support the claim made by the teaching professional, what null and alternative hypotheses should you test? Ho: μ = $2,200 Ha: # $2,200 b. Suppose you select a = 0.10. Interpret this value in the words of the problem. The probablility that the null hypothesis is when the average gain $2,200 is 0.10.
