Question

Consider the hypotheses shown below. Given that x = 45, o = 12, n=38, a = 0.01, complete parts a and b. Ho:us 43 Hy: u > 43 a

Answer 1

Answer #1

From the given information,

By using calculator,

The required correct answers are,

a. z-test statistic= 1.03

Critical value= 2.3265

As z-test statistic < Critical value

Fail to reject null hypothesis.

Conclusion: mean(mu) ≤ 43

b. P-value= 0.1521

Thank you.
