When p = 12, t = 2, and s = 1/6, r = 18. If r varies directly with p and inversely with the product of s and t, what is the cons

Ilia_Sergeevich [38]

R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2

Determine the critical value or values for a one-mean z-test at the 10% significance level if the hypothesis test is left-tailed

Ugo [173]

Answer: 1.282

Step-by-step explanation:

Given : Significance level : $\alpha= 10\%=0.10$

The alternative hypothesis : $H_a:\mu$ , which is left tail-ed , it means the test is left -tailed test i.e. one -tailed test.

By using the standard normal distribution table , we have

The critical value for a one-mean z-test corresponding to the significance level 0.10 is 1.2815515 or approximately 1.282

Hence, the critical value or values for a one-mean z-test at the 10% significance level if the hypothesis test is left-tailed = 1.282
