Compute the value of the test statistic
The null and alternate hypotheses are: Ho Maso HP>0 The following sample information shows the number of defective units produced on the day shift and the afternoon shift for a sample of four days last month. Day 2 12 10 1 10 9 Day shift Afternoon shift 13 14 4 18 15 At the 0.050 significance level, can we conclude there are more defects produced on the day shift? Hint: For the calculations,...
The one-sample t-statistic for a test of Ho: = 42 versus H:# < 42 based on n = 15 observations has the value t = -2.138, where H, and Hare the null and alternative hypotheses, respectively. The sample size is denoted by n.
The test statistic of zs -2.78 is obtained when testing the claim that p <0.46. a. Using a significance level of a=0.01, find the critical value(s). b. Should we reject He or should we fail to reject H? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. The critical value(s) is/are z= (Round to two decimal places as needed. Use a comma to separate...
