Math 225n final exam

1/1 POINTS A fitness center claims that the mean amount of time that a person spends at the gymper visit is 33 minutes. Identify the null hypothesis, H0, and the alternative hypothesis, Ha, in terms of the parameter μ. That is correct! H 0 : μ ≠ 3 3 ; H a : μ = 33H0:μ=33;Ha:μ≠33H0:μ ≥33;Ha:μ<33H0:μ≤33;Ha : μ > 3 3 Answer Explanation Correct answer: H0: μ=33; Ha: μ≠33 Let the parameter μ 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 orequal to (≤). Therefore, in this case, the null hypothesis H0 is μ=33. The alternative hypothesis is contradictory to the null hypothesis, so Ha is μ≠33. Q U E S T I O N 2 1 / 1 P O I N T S The answer choices below represent different hypothesis tests.
