Let H 0 80 Vs H 1 Gt 80 We Obtain The Following Result By Empirical Study 1 Calc

Let H0: μ≤80 vs H1:µ>80.

We obtain the following result by empirical study:

(1) Calculate the test statistic zcalc

(2) Find p-value for the sample.

(Hint p-value = P(Z>zcalc)=1−P(Z<zcalc), where Z~N(0,1))

(3) Is H0 rejected by the right tailed test for significant level at α=0.05?

Here,     is the sample mean, σ is the population standard deviation, and n is the number of samples.

Use the attached table for Z~N(0,1) .
