QuestionClaim: The mean pulse rate (in beats per minute) of adult males is equal to 69.2 bpm . For a random sample of 175 adult males, the mean pulse rate is 69.5 bpm and the standard deviation is 10.8 bpm . Complete parts (a) and (b) below. a. Express the original claim in symbolic form. $\square$ $\square$ $\square$ bpm (Type an integer or a decimal. Do not round.) b. Identify the null and alternative hypotheses. $\mathrm{H}_{0}$ : $\square$ $\square$ $\square$ bpm $\mathrm{H}_{1}$ : $\square$ $\square$ bpm (Type integers or decimals. Do not round.)

Studdy Solution
Identify the null hypothesis ( $H_0$ ) and the alternative hypothesis ( $H_1$ ):
$H_0: \mu = 69.2 \, \text{bpm}$
$H_1: \mu \neq 69.2 \, \text{bpm}$
The original claim in symbolic form is:
$\mu = 69.2 \, \text{bpm}$
The null and alternative hypotheses are:
$H_0: \mu = 69.2 \, \text{bpm}$
$H_1: \mu \neq 69.2 \, \text{bpm}$
