Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69.569.5 bpm.
For a random sample of 131131 adult males, the mean pulse rate is 69.969.9 bpm and the standard deviation is 11.311.3 bpm. Complete the parts below.
(a) Express the original claim in symbolic form.
(b) Identify the null and alternative hypotheses.

a)

b) Null hypothesis:

Alternative hypothesis:

And we can use a t test procedure in order to check if the true mean is equat to the desired value.

Step-by-step explanation:

For this case we know that this:

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69.5 bpm

Part a

If we convert this with symbols we can write this as:

Part b

We have the following info given:

represent the sample mean

represent the sample size

We have the following system of hypothesis:

Null hypothesis:

Alternative hypothesis:

And we can use a t test procedure in order to check if the true mean is equat to the desired value.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your
