A kinesiologist claims that the resting heart rate of men aged 18 to 25 who exercise regularly is less than that of men who do not exercise regularly. Men in each category were selected at random and their resting heart rates were measured, with the following results: n Regular exercise 40 63 1.0 No regular exercise 30 71 1.2 (a) Set up the appropriate H0 and Ha. (b) Propose a formula to calculate the test statistic and report the result. (c) Find the P-value and make your conclusion on α = .05.

Expert Solution

Step 1

Group 1: Regular exercise

$x_{1} = 63, n = 40 a n d s = 1.0$

Group 2 : No Regular exercise

$x_{2} = 71, n = 30 a n d s = 1.2$

(a) $H_{0} : μ_{1} = μ_{2} = 0$

$H_{1} : μ_{1} = μ_{2} > 0$
