Use the given information to find the Pvalue Also use a 005

Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a right-tailed test is z = 1.43.

Solution

for alpha = 0.05

looking in the talbes of Z distribution

critical value is 1.64

we fail to reject Ho because Z is lower tha n critical value

fail to reject the null hypothesis
