Researchers conducted a study and obtained a p-value of 0.75. Based on this p-value, what conclusion should the researchers draw?Choose the correct answer below.O A. Reject the null hypothesis and accept the alternative as true.OB. Redo the study as it is not possible to get a p-value that high.OC. Reject the null hypothesis but do not accept the alternative as true.(・・・)O D. Fail to reject the null hypothesis and, therefore, accept the null hypothesis as true.O E. Fail to reject the null hypothesis but do not accept the null hypothesis as true either.

When p value is too large or greater than level of significance ɑ=0.05, then we fail to reject the…

60% of students entering four-year colleges receive a degree within six years. Is this percent smaller than for students who play intramural sports? 130 of the 241 students who played intramural sports received a degree within six years. What can be concluded at the level of significance of a = 0.01? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho:1?v Но: 7Select an answer v (please enter a decimal) H1:1?v|Select an answer v (Please enter a decimal) c. The test statistic ?

Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusiion is that .. The data suggest the population proportion is not significantly smaller than 60% at a = 0.01, so there is not sufficient evidence to conclude that the population proportion of students who played intramural sports who received…
A study is designed to determine the effect of an office-training course on typing productivity. Fifteen typists who have not taken the course are randomly selected. The investigator assigns 20 pages of equally difficult text to be typed by each typist both before and after completing the training course. The investigator wants to find out whether the training course has reduced the number of errors by more than 10. Define d Before - After. What is the alternative hypothesis for this test? Ha: ud > 0 Ha: ud 10. Ha: ud 10 Ha: ud-10
