Question

In an effort to improve final grades in her class, a professor tried a new method of evaluation with one of her intro stats classes last term. A test of the null hypothesis that her old method (used with one class) and new method (used with her other class) dont differ in the mean final grade for students yielded a p-value of 0.095. Would a 95% confidence interval for Hold-Hnew include 0? Explain your answer

Answer 1

Answer #1

yes, 95% confidence interval will include zero,

since p-value =0.095>alpha=0.05

so, do not reject Ho

hence, confidence will give the same result ,so confidence interval will give result do not reject Ho,and this will happen if 95% confidence interval will include zero

A professor marks an exam and, after compilation of the grades,she finds that her 25 students obtained a class mean of 70%. On the other hand, the median is 74% and the mode is 78%. a) At least how many students scored 74% or more?

In one statistics class, students were given one homework assignment. The professor asked students to find an example of a multinomial population and then to develop a hypothesis test. One student found an example – He selected four classes in fall 2010: Management, Accounting, Finance, and Economics. He computed the proportion of students who received an A grade for each class in fall 2010. The proportion of students who received an A grade in Management (M), Accounting (A), Finance (F),...

A professor gives his class a final examination that he knows from years of experience yields a population mean of 84. His present class of 24 obtains a mean of 88 and a standard deviation of 8. Is he correct in assuming that the performance of the most recent class differs significantly from that of other classes? Use a one-tailed test here since the professor assumes that the class will score higher. Null hypothesis: Alternative hypothesis: Statistical test: Significance level...

The professor decides to reuse a final exam that was first administered 10 years ago. At that time the mean score was 81 with s=10, for the 50 students in the section taught by that professor When given to the current class of 53 students, who observed essentially the same set of lectures, the mean is 75 with s=15.
