MATH 225N Week 8 Final ExamQuestion 11/1 pointsA fitness center claims that the mean amount of time that a person spends at the gym per visit is 33 minutes. Identify the null hypothesis, H 0 , and the alternative hypothesis, Ha , in terms of the parameter .That is correct!H 0 : 33 ; Ha : =33H 0 : =33 ; Ha : 33H 0 : 33 ; Ha : 33Answer ExplanationCorrect answer:H 0 : =33 ; Ha : 33Let the parameter be used to represent the mean. The null hypothesis is always stated with some form of equality: equal ( = ), greater than or equal to ( ), or less than or equal to ( ). Therefore, in this case, the null hypothesis H 0 is =33 . The alternative hypothesis is contradictory to the null hypothesis, so Ha is 33 .Question 21/1 pointsThe answer choices below represent different hypothesis tests. Which of the choices are right-tailed tests? Select all correct answers.That is correct!H 0: X 17.1 , Ha : X 3.8H 0: X 7.4 , Ha : X >7.4H 0: X =3.3 , Ha : X 3.3Answer ExplanationCorrect answer:H 0: X 3.8 , Ha : X >3.8H
