The standard deviation of pulse rates of adult males is less than 12 bpm. For a random sample of 135 adult males, the pulse rates have a standard deviation of 11.5 bpm. Complete parts (a) and (b) below. a. Express the original claim in symbolic form.

The population variance is symbolized σ² and the standard deviation σ (remember that for estimations and statistics test, the parameter of study is always the variance)

The sentence "The standard deviation of pulse rates of adult males is less than 12 bpm." is symbolized σ <12

The sample variance is symbolized S² and the standard deviation is S.

The sample standard deviation is S= 11.5.

I hope it helps!
