He believes that his senior students spend more time studyin per week than his freshmen studnet and decides to perform a hypothesis test on his belief. a. Suppose the decision of the hypothesis test is to reject the null hypothesis. If, in realiry, treshmen study for a mean of 10 hours per week and seniors study for a mena of 15 hours per week, was an error made? if so, what type? b.

In a specific population of adult migraine sufferers in the US, the average number of migraines per month is 9. An acupuncturist claims that her treatment can reduce this figure significantly. On your own scrap paper, explore the possible errors with a Type 1/2 error chart, making note of the meaning of each possibility. Decision H0H0 is Actually True False Reject H0H0 and Accept HaHa Fail to Reject H0H0 Select the Null and Alternative Hypotheses to the scenario using the correct symbols. H0H0: μ<9μ<9HaHa: μ=9μ=9 H0H0: μ>9μ>9HaHa: μ=9μ=9 H0H0: μ=9μ=9HaHa: μ>9μ>9 H0H0: μ=9μ=9HaHa: μ<9μ<9 Explain what a type 1 error is in this scenario. A type 1 error would be concluding that the migraine treatment can reduce occurence of frequent migraines when in fact, it can.
