SOLUTION:

From given data,

Claim: The mean pulse rate​ (in beats per​ minute) of adult males is equal to 69.4 bpm. For a random sample of 170 adult​ males, the mean pulse rate is 70.6 bpm and the standard deviation is 11.4 bpm.

sample size = 170

standard deviation= 11.4 bpm

mean = 70.6

(a). Express the original claim in symbolic form

Here claim is that the mean pulse rate (in beats per minute) of adult males is equal to 69.4

So, claim is = 69.4

(b) Identify the null and alternative hypotheses.

Null hypothesis:

The null hypothesis is the mean pulse rate of adult males is equal to 69.4 bpm

That is,

:   = 69.4

Alternative hypothesis:

The alternative hypothesis is the mean pulse rate of adult males is differ from 69.4 bpm

That is,

:     69.4

dear, sir/ma'm ... you posted incomplete question so as per my knowledge on this question i was posted complete answer with part (a) and part (b)....if there is any changes in the answer please suggest me ....
