You decide to test the claim that the mean Age of TCC students is less than 30 at the . 05 significance level. From your sample of
$9students, the mean age was 27.4 , with a standard deviation of 9.2 years. The alternative loypothesis is:
H_(a):p<30
◻
H_(0):x<30
H_(4):\mu !=30
◻
H_(a):\mu <30
H_(4):p!=30The Test Statistic is: Round to 2 decimal places. The d -value is:
q,Round to 4 decimal places. Our conclusion is: fluefer the rutt hopothesis Fall to reject our hypothesis Fall to reject the null hypothesis Reject our typothesis
