Answer:
We need to conduct a hypothesis in order to check if the true mean is different from 45(alternative hypothesis), and then the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we don't know the sample size we can't calculate the statistic and the only thing that we can do is create the sytem of hypothesis.
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
