While conducting a 1 tailed hypothesis test, you found that the p-value is 0.016. If α = 1%, what would your decision be? Question 10 0 out of 6 points The average SAT score of students at NYU is 1340. Professor Mazza believes it is higher. What is the alternative hypothesis? Question 11 0 out of 6 points The average amount of time that students spend studying is 280 minutes per week with a standard deviation of 22 minutes. Dr. Mazza believes this is incorrect. If α = 5%, which of the following would be your decision rule? Question 12 0 out of 6 points According to a recent insurance company claim an American family of four spends a mean of $2000 per year for medical care. The medical association believes this claim is too low. What is the alternative hypothesis?

Expert Solution

While conducting a 1 tailed hypothesis test, you found that the p-value is 0.016. If α = 1%, what would your decision be?

Since p-value is more than 0.01, we do not reject the null hypothesis.

10. The average SAT score of students at NYU is 1340. Professor Mazza believes it is higher. What is the alternative hypothesis?

H1: µ > 1340

11. The average amount of time that students spend studying is 280 minutes per week with a standard deviation of 22 minutes. Dr. Mazza believes this is incorrect. If α = 5%, which of the following would be your decision rule?

H0: µ = 22

H1: µ > 22

If p-value is less than 0.05, reject the null hypothesis. Else, do not reject the null hypothesis.

12. According to a recent insurance company claim an American family of four spends a mean of $2000 per year for medical care. The medical association believes this claim is too low. What is the alternative hypothesis?

H1: µ > 2000
