In a random sample of 400 items where 86 were found to be​ defective, the null hypothesis that 20​% of the items in the population are defective produced Upper Z Subscript STAT=+0.75. Suppose someone is testing the null hypothesis Upper H0​: pi=0.20 against the​ two-tail alternative hypothesis Upper H1​: pi≠0.2 and they choose the level of significance α=0.05 What is their statistical​ decision?

    10) A set of data was collected involving the number of defective items found in a random sample of 46 cases of light bulbs produced during a morning shift at a plant. A manager wants to know if the mean number of defective bulbs per case is greater than 20 during the morning shift. She will make her decision using a test with a level of significance of 0.10. The following information was determined for the sample of 46 cases:...

    Independent random samples of size n1=38 and n2=86 observations, were selected from two populations. The samples from populations 1 and 2 produced x1=18 and x2=13 successes, respectively. Define p1 and p2 to be the proportion of successes in populations 1 and 2, respectively. We would like to test the following hypotheses: H0:p1=p2 versus H1:p1≠p2 (a)To test H0 versus H1, which inference procedure should you use? A. Two-sample z procedure B. One-sample z procedure C. One-sample t procedure D. Two-sample t...
