Make the decision in each test based on the information prov

Make the decision in each test, based on the information provided.

a) Testing H0:=31.4 vs. Ha:>31.4 @ =0.10, observed significance p = 0.062.

b) Testing H0:=75.5 vs. Ha:<75.5 @ =0.05, observed significance p = 0.062.

Solution

a    p = 0.062     alpha = 0.10    as p<alpha

hence ho is rejected therefore alternate hypothesis is accepted

Ha:>31.4

b p = 0.062    alpha = 0.05      as p>alpha

hence ho cannot be rejected

=75.5
