Long-Range Discs manufactures discs for playing disc golf. The company is developing two different models of distance drivers, the Lightning and the Thunder. Tatiana Purslow, an engineer for Long-Range Discs, is verifying whether the population mean flight distance of the Lightning is different than the population mean flight distance of the Thunder to prevent redundant models of discs from being manufactured. Tatiana reviews the specifications of the discs and assumes that the population standard deviation of the flight distance is 10.87 m for the Lightning and 11.13 m for the Thunder. She randomly selects a sample of discs for each model and then tests the flight distance of each disc using a robotic device that throws the discs at the same speed. The results of the test are shown in the table below. Let α = 0.10, be the population mean flight distance of the Lightning, and H2 be the population mean flight distance of the Thunder. If the test statistic is zR 2.84 and the rejection region is less than -z0o 1.645 or greater than zo.0s 1.645, what conclusion could be made about the population mean flight distance for both models of discs? Identify all of the appropriate conclusions. Lightning -,-120.57 m 1140 Thunder X2 = 1 16.79 m n-= 134 Select all that apply:

Reject the null hypothesis.
Fail to reject the null hypothesis.
There is insufficient evidence at the α=0.10 level of significance to conclude that the population
mean flight distance of the Lightning is different than the population mean flight distance of the Thunder.
