Question
Assuming that you are to test the following hypothesis using the above information and a critical Z-value approach at a 5% significance level. H_0: mu = 10.5 vs. H_1: mu notequalto 10.5 you would find the calculated Z-value, Z_c, to be _____ and the critical (or table) Z-value to be _____. 0.33; 1.96 0.33; 1.645 1.67; 1.96 1.67; 1.645 1.96; 1.96 Assuming that you are to test the following hypothesis using the above information and a critical Z-value approach at a 5% significance level, H_0: mu greaterthanorequalto 10.5 vs. H_1: muExplanation / Answer
Q36)
Critical z value from normal table we get as -1.645
We cannot calculate test statistics here as sample mean, standard deviations and sample size are not given here.
Q37)
Answer: d. only (a) and ( c) of the above
Explanations:
The decision rule of the left-tailed test if the Z-value is less than the Critical Z, we reject the null hypothesis. Here the Z-value is greater than the critical value so we fail to reject or accept the null hypothesis.
