Claim: 52,200 = 0.05 Sample statistics: 53, 220, s-1200, n-4Explanation / Answer
SOLUTION22:
t=1.705
tcrit=1.725
t<tcrit
ACCEPT NULL HYPOTHESIS
SOLUTION23:
t=-1.755
tcal=|-1.755|
=1.755
t crit=1.725
t cal> tcrit
REJECT NULL HYPOTHESIS
SOLUTION24:
Tcal=1.745
t crit=1.725
tcal> t crit
REJECT NULL HYPOTHESIS
