What z Score do we need in order to have a total of 5% (or less) error in the design?
A. 1.00
B. 1.50
C. 1.96
D. 1.65
Total 2 tailed error should be 5% or less. Hence,
z score required = z score corresponding to 2.5% area to the right = 1.96
Option C is correct.

1. Regarding a two-tailed z-test with an alpha of 0.05, we would need a Zobt with an absolute value less than 1.96 in order to reject the null hypothesis. True or False? 2. What happens to the probability of committing a Type I error if the level of significance is changed from α = 0.05 to α = 0.01? A. It increases B. It decreases C. It stays the same D. Cannot determine 3. Given a Zobt of -1.99 ,...

Identify the Z-Score value corresponding to each of the following locations: Below the mean by a standard deviation of 1 Above the mean by a standard deviation of 1 and 1/2 Below the mean by standard deviation of 3/4 Above the mean by a standard deviation of 2 and 7/8 a. Z = 1.00 Z = 1.50 Z = .75 Z = 2.875 b. Z = -1.00 Z = +1.50 Z = -.75 Z = +2.875 c. Z = +1.00...

There are a few z scores that we use often that are worth remembering. The upper 50%, and 97.5 percent of a normal distribution are cut off by z scores of O a. 0.0, and 1.96 Ob. 1.0, and 1.64 C. plus and minus 1.96 d..50, and .975 QUESTION 11 If we have data that have been sampled from a population that is normally distributed with a mean of 50 and a standard deviation of...
