An experiment to determine the most effective way to teach safety principles applied four different teaching methods. Some employees were given programmed instruction booklets and worked through the course at their own pace. Other employees attended lectures. A third group watched a television presentation, and a fourth group was divided into small discussion groups. A high of 10 was possible. A sample of five tests was selected from each group. The test grade results were:
At the 0.01 level, what is the critical value?
Stock form a normal distribution with a mean of $8.52 with a standard deviation of 2.38. What percentage of the scores lie below $7.42?
Compute the pdf of continuous random variable Z where Z = X + Y and X is a continuous random variable uniformly distributed on [0, 2] and Y is a continuous random variable uniformly distributed on [0, 4]. Assume that X and Y are independent.
A population consists of ten items, six of which are defective. In a sample of three items, what is the probability that exactly two are defective?
The critical value of F at 95% confidence when there is a sample size of 21 for the sample with the smaller variance, and there is a sample size of 9 for the sample with the larger sample variance is:
Compute mean, variance, and standard deviation of number of parents who correctly recognize their child's illness. Determine the probability at most five parents are correct.
Draw a sketch of the standard normal distribution curves, one for the current process and another one for the recentered process. Label the spec limits and shade the area of the curve that corresponds to your answer.
Are the following statements a valid pair of null and alternative hypothesis?
Draw a column chart from grade book. Use column illustrating students' names; select one of the tests to plot.
What sample size must you take to be 96% confident that the results will be within $.75 of the true mean cost per call?
Within distribution of scores, measures of dispersion give an indication of?
Statisticians prefer large samples. Describe briefly the effect of increasing the size of a sample on each of the following: The margin of error of a 95% confidence interval?
Perform a significance test to assess whether there is an association between mortality from cirrhosis of the liver and duration of employment in the group hired after 1945. Report a p- value.
