Question

Claim: The mean pulse rate​ (in beats per​ minute) of adult males is equal to 69.569.5 bpm.

Answer 1

Answer:

a) $\mu =69.5$

b) Null hypothesis: $\mu =69.5$

Alternative hypothesis: $\mu \neq 69.5$

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:

$\mu =69.5$

Part b

We have the following info given:

$\bar X= 69.9$ represent the sample mean

$n =131$ represent the sample size

We have the following system of hypothesis:

Null hypothesis: $\mu =69.5$

Alternative hypothesis: $\mu \neq 69.5$

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