Answer:
a) [tex]\mu =69.5[/tex]
b) Null hypothesis: [tex]\mu =69.5[/tex]
Alternative hypothesis: [tex]\mu \neq 69.5[/tex]
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:
[tex]\mu =69.5[/tex]
Part b
We have the following info given:
[tex]\bar X= 69.9[/tex] represent the sample mean
[tex] n =131[/tex] represent the sample size
We have the following system of hypothesis:
Null hypothesis: [tex]\mu =69.5[/tex]
Alternative hypothesis: [tex]\mu \neq 69.5[/tex]
And we can use a t test procedure in order to check if the true mean is equat to the desired value.
