Part A. Express the original claim in symbolic form.

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.

Therefore, the original claim in symbolic form is:

ANSWER:

[tex]\mu=68.9\text{ bpm}[/tex]

Part B. Identify the null and alternative hypotheses.

[tex]\begin{gathered} H_0\colon\text{ }\mu=68.9\text{ bpm} \\ H_1\colon\mu\ne68.9\text{ bpm} \end{gathered}[/tex][tex]\begin{gathered} H_0\text{ or the null hypothesis will be based to our claim. We will test if the mean pulse} \\ \text{rate of an adult male is equal to 68.9 bpm.} \\ H_1\text{ or the alternative hypothesis is the one that contradicts the null hypothesis. That is } \\ \text{why our H}_a\text{ has the sign of not equal to (}\ne). \end{gathered}[/tex]
