Answer:
Null hypothesis:
Alternative hypothesis:
Or equivalently :
Null hypothesis:
Alternative hypothesis:
Explanation:
Data given and notation
represent the sample mean
represent the sample standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the true mean is lower than 10.1 ft (alternative hypothesis) , then the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Or equivalently :
Null hypothesis:
Alternative hypothesis:
