the entire herd is 5.1 pounds, test the hypothesis that the average weight gain per cow for the month was more than 7 pounds. Null Hypothesis: Ho: II = 7 Alternative Hypothesis: Ha: u > 7 (a) Calculate the test statistic. (Round your answer to two decimal places.) 2 = E] x i - u z: 0/]; (b) Calculate the Pvalue. (Use a table or technology. Round your answer to four decimal places.) .372 x Decide what the symbol in the alternative hypothesis is and then use the Standard Normal Probabilities Table or technology
