Suppose a study was done to determine if the average amount of sleep that students get the day before an exam is less than 6 hours.An SRS of 100 students from a university was taken and a mean of 5.5 hours was computed from the sample.The figure below provides the results of the analysis. What is the alternative hypothesis? A)H_a: $\mu$ = 6 B)H_a: $\mu$

Suppose a study was done to determine if the average amount of sleep that students get the day before an exam is less than 6 hours.An SRS of 100 students from a university was taken and a mean of 5.5 hours was computed from the sample.The figure below provides the results of the analysis. What is the alternative hypothesis? A)H_a: $\mu$ = 6 B)H_a: $\mu$ < 6 C)H_a: $\mu$ < 5.5 D)H_a: $\mu$ = 5.5 E)H_a: $\mu$ > 6

Quizplus · Accepted Answer

The alternative hypothesis should state that the mean amount of sleep is less than 6 hours, as that is what the study is investigating. Choice B is the only option that accurately reflects this.
