Suppose the weights of seventh-graders at a certain school vary according to a Normal distribution, with a mean of 100 pounds and a standard deviation of 7.5 pounds. A researcher believes the average weight has decreased since the implementation of a new breakfast and lunch program at the school. She finds, in a random sample of 35 students, an average weight of 98 pounds. What is the P-value for an appropriate hypothesis test of the researcher's claim? 0.057 -1.578 0.943 O 0.115
