When using a one-tailed test, you are testing for the possibility of the relationship in one direction and completely disregarding the possibility of a relationship in the other direction. Let’s return to our example comparing the mean of a sample to a given value x using a t-test. Our null hypothesis is that the mean is equal to x. A one-tailed test will test either if the mean is significantly greater than x or if the mean is significantly less than x, but not both.
in this question,
we are testing the hypothesis
Ho: New math is more effective than traditional math
H1: New math is equally or less effective than traditional math
so, here she will conduct one-tailed hypothesis test

A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with mu equalsμ=519519. The teacher obtains a random sample of 20002000 students, puts them through the review class, and finds that the mean math score of the 20002000 students is 525525 with a standard deviation of 114114. Complete parts (a) through...

A graduate student in education has developed an mathematical intervention program for under-performing school children. To test the effectiveness of his intervention he administers a math skills assessment at the beginning of the school year to a sample of n-25 students. He then implements the program throughout the year and re-assess the students again at the end of the school year. On average there was a 3 point difference between time 1 and time 2, with a variance value of...

Professor Francis has implemented a new book for his Fall 2013 statistics course. He wants to see if the new book has an effect on the exam average for Exam 3. He knows that the Exam 3 mean for all students who have taken his statistic course over the past 10 years is 77.2. He collects some data from a sample of 9 students and finds that the Exam 3 mean for his Fall 2013 statistics students is 81.7 with...

You conduct an experiment on whether a new treatment for chronic dry mouth is more effective than the traditional treatment at relieving chronic dry mouth. Analyzing your results, you calculate a Bayes factor of 0.5. What does this mean? a. Evidence suggests that the new treatment is 5 times more likely than the traditional treatment at relieving chronic dry mouth. b. Evidence suggests that the new treatment is 5 times less likely than the traditional treatment at relieving chronic dry...

The Acme Drug Company develops a new drug, designed to prevent colds. The company states that the drug is more effective for women than for men. To test this claim, they choose a simple random sample of 100 women and 200 men from a population of 100,000 volunteers. At the end of the study, 38 of the women caught a cold; and 102 of the men caught a cold. Based on these findings, can we conclude that the drug is...
