Question

claim: the standard deviation of pulse rates of adult males is less than 10 bpm. for a random sample of 167 adult males, the pulse rates have a standard deviation of 8.7 bpm. complete parts (a) and (b) below a. express the original claim in symbolic form. bpm (type an integer or a decimal. do not round.)

Explanation:

Step1: Determine the symbol for standard deviation

In statistics, the symbol for population standard deviation is \(\sigma\).

Step2: Translate the claim into symbolic form

The claim is "the standard deviation of pulse rates of adult males is less than 10 bpm". So, we use the inequality symbol \( < \).

Answer:

\(\sigma < 10\)
