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 ....

The mean pulse rate of the entire population of adult
men is 70 beats per minute. A sample of 10 adult male patients is
given a new drug, and after several minutes, their mean pulse rate
is measured at 75 beats per minute with a standard deviation of 8
bpm. Do I have sufficient evidence to support my claim that this
drug is effective in raising the heart beat of male
patients?

It is generally accepted that the mean heart rate (beats per
minute; bpm) of an adult human is between 65 bpm and 75 bpm, with a
single average value of 72 bpm. In this case study you will test
the hypothesis that the average heart rate of adults is 72 bpm (μ =
72 bpm) for all adults and then separately by gender. The
distribution of heart rates is approximately normal.

is 10. Find:
a. The probability that a randomly chosen adult has a pulse rate
over 78 assuming that the rates are normally distributed.
The probability that a random sample of 19 adults will have a
mean score over 78.
