Ho: µ 2 50 for our test. The sample size is 30 and the significance level is 0.04. If the test statistic is -2.04 is a Type I error possible? Explain. 5.
Please include the critical value/s with its interpretation, the p-value and its interpretation. Only a very basic and little work-through is required for all steps. Thank you
All other conditions being equal, does a larger sample size increase or decrease the corresponding magnitude of the z or t value of the sample test statistic?
i can come up with the correct answer to these two types of problems. I know I am just missing a small piece of it. hypothesist test for single population mean and single population proportion. need to figure out test statistic . and "p" value 2. 20% all college students volunteer their time. is the percentage of college student who are volunteers different for students receiving financial aid? of the 387 randomly selected students who receive financial aid, 58 of them volunteered their time. what can be concluded at the alpha 0.05 level of significance. Need to figure test statistic and "p" value.
