In this example, the critical value is 3.8. The Chi-square value was 2.383, which is less than 3.8. Thus, there is no significant difference in handedness between men and women in our sample.

Jan 09, 2013 · Since there are 18 – 1 = 17 degrees of freedom and we want 99% confidence, we will use a critical value of t* = 2.898. = = 24.94 1.95 = (22.99, 26.89) Conclude: We are 99% confident that the interval from 22.99 squares to 26.89 squares captures the true mean number of squares of generic toilet paper needed to absorb 1/4 cup of water.

Value analysis is not a critical review, constructability review, or cost cutting exercise. It is a problem solving and decision making technique that bypasses learned responses to produce alternative solutions achieving all required functions of the original design at the least cost over the life of the facility.

Make your statistical decision by comparing the z-score for the Shmerkeley sample with the appropriate critical value for a two-tailed test. Would a two-tailed test be significant in this case? Repeat part (a) for a random sample of 64 students, who also have a mean of 530 on the SAT. If your results are different from part (a), describe why.
