Claim: the mean pulse rate (in beats per minute, or bpm) of adult males is equal to 69 bpm. for the random sample of 153 adult males in data set 1 "body data" in appendix b, the mean pulse rate is 69.6 bpm and the standard deviation is 11.3 bpm. only identify the null and alternative hypothesis.

Step-by-step explanation:

We know that ,

Null hypothesis is a statement that contains the population parameter to represent claim or against claim statement along with = , ≤ and ≥ signs.

Where as Alternative hypothesis is also a statement that contains the population parameter but against the null hypothesis . It contains ≠ , < and > signs.

In the given situation, the population parameter is population mean .

Claim: The mean pulse rate (in beats per minute, or bpm) of adult males is equal to 69 bpm.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
