Question

Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis. b) one-tail test. z. _ 2.15, and -0.01 d) two-tail test, z-1.77, and -o.02 a) one-tail test. z. = 1.40, and = 0.05 c) two-tail test, z" 2.50, and -005 Click here to view page 2 of the cumulative probabilities for the standard normal distribution a) The p-value is Round to four decimal places as needed.) , re to view page 1 of the cumulative probabilities for the standard normal distribution

Explanation / Answer

a) P-value = P(Z > 1.4) = 1 - P(Z < 1.4) = 1 - 0.9192 = 0.0808

Since, p-value is not less than 0.05, we do not reject the null hypothesis

b) P-value = P(Z < -2.15) = 0.0158

Since, p-value is not less than 0.01, we do not reject the null hypothesis

c) P-value = 2 * P(Z > 2.5) = 2 * (1 - P(Z < 2.5)) = 2 * (1 - 0.9938) = 0.0124

Since, p-value is less than 0.05, we reject the null hypothesis.

d) P-value = 2 * P(Z < -1.77) = 2 * 0.0384 = 0.0768

Since, p-value is not less than 0.02, we do not reject the null hypothesis
