34.Which of the following correctly represents Z normal deviate?  A. (Sample mean - Population mean)*standard error  B. (Sample mean - Population mean)/standard error  C. Standard error/(Sample mean - Population mean)  D. Standard error + (Sample mean - Population mean)

33.What does the null hypothesis for normal deviate z test state?  A. There is no significance difference between your sample and population. The small difference is due to statistical fluctuations.  B. There is a significance difference between your sample and population.  C. The sample given to you and the population are not at all related.  D. The population is a subset of the sample given to you.

Which of these z-scores might represent a very difficult item in the normal distribution?a.+2.33b.−.52c.−2.06d.+.20

What is the mean of the z-scores?Question 2Answera.0.5b.0c.1

Sample Z-Score and Standard ErrorSuppose the population has a mean of 350 and a standard deviation of 90, and you get a sample mean of 370.16 for a sample size of 36, what will be the sample z-score?9.721.34153.83

The formula for calculating the z-statistic is:a.(Sample mean - Population mean) / Sample standard deviationb.(Sample mean - Population mean) / Population standard deviationc.(Sample mean - Population mean) / Square root of sample sized.(Sample mean - Population mean) / Square root of population size
