Suppose a sample size of 87 was used to conduct a right tailed hypothesis test for a single population mean. The null |hypothesis was Ho: µ 45 and the sample mean was 50 and the p-value was 0.03. Then there is a 3% chance that 87 randomly selected individuals from a population with a mean of 45 and the same standard deviation would have a sample mean greater than 50. false true A researcher wants to test the hypothesis that college students weigh less on average than the average American (160 Ibs). The sample mean of the 80 students who were weighed was found to be 142 pounds and the P-value was 0.03. This means that if the mean of all students' weight is 160 lbs, then there would be only a 3% chance that a randomly selected group of 80 students would have a mean weight of less than 142 lbs. false true
