In a test of H0 u30 against Ha u30 the sample data yeilded t

In a test of H0: u=30 against Ha: u>30 the sample data yeilded the test statistic z=2.10.

Find the p-value for the test. Round to four decimal places.

Solution

H0: u = 30
Ha: u > 30

test statistic,z = 2.10

Since it is a right-tailed test, hence
P_value = P(Z> 2.10 )
= 1 - P(Z< 2.10 )
= 1 - 0.9821
= 0.0179
