Arianna Estefan manages Salmon Falls Park, which has two flagship roller coasters, the Flyer and the Destroyer. When Arianna walks around the park during hours of operation, she notices that there are fewer people waiting in line for the Flyer than for the Destroyer. Since both roller coasters have similar capacities and similar run times, both roller coasters should have about the same number of riders. Based on the anecdotal evidence, Arianna claims that the population mean number of riders per hour on the Flyer is less than the population mean number of riders per hour on the Destroyer. Arianna reviews data collected in the past and assumes that the population standard deviation is 48.29 for the Flyer and 51.86 for the Destroyer. Arianna randomly selects hours during which the attendant of each ride counts the number of riders. The sampling occurs over the course of several weeks. The results are provided in the table shown below. Let H be the population mean number of riders per hour on the Flyer and u2 be the population mean number of riders per hour on the Destroyer. What type of test is this hypothesis test? Flyer Destroyer X2 = 124.71 n2 51 109.62 n 54

Select the correct answer below:

 

This is a two-tailed test because the alternative hypothesis is Ha:μ1−μ2≠0.

 

This is a right-tailed test because the alternative hypothesis is Ha:μ1−μ2>0.

 

This is a right-tailed test because the alternative hypothesis is Ha:μ1−μ2<0.

 

This is a left-tailed test because the alternative hypothesis is Ha:μ1−μ2<0.

 

This is a left-tailed test because the alternative hypothesis is Ha:μ1−μ2>0.
