Answer:
Now we can find the p value based in the alternative hypothesis and we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if the true mean for this case is 64 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
The statistic for this case is given by:
Now we can find the p value based in the alternative hypothesis and we got:
