Determine the pvalue for the following hypothesis tests invo

Determine the p-value for the following hypothesis tests involving Student\'s t-distribution with 15 degrees of freedom. (Give your answers correct to three decimal places.)

Solution

a)
U=14 , H1: U<14
P-Value :Left Tail -Ha : ( P < 1.3 ) = 0.107
b)
U=14 , H1: U>14
P-Value :Left Tail -Ha : ( P < 1.3 ) = 0.107

c)
U=14 , H1: U>14
P-Value :Two Tailed ( double the one tail ) -Ha : ( P != 1.3 ) = 0.213
d)
U=14 , H1: U>14
P-Value :Two Tailed ( double the one tail ) -Ha : ( P != -1.3 ) = 0.213
