A researcher wishes to see if there is a difference in the manual dexterity of athletes and that of band members. Two random samples of 22 are selected from each group and are given a manual dexterity test. The mean of the athletes' test was 87, and the mean of the band members' test was 93. The population standard deviation for the test is 7.6. Use μ1 for the mean of the athletes' test. At =α0.05, is there a difference in the mean scores? Use the P-value method and tables.

A) Compute the test. Find the Z score

B) Compute the P value.

C) Reject or do not reject the null hypothesis.

D) Is there or is their not enough evidence to support the claim.

An educational researcher devised a wooden toy assembly project to test learning in 6-year-olds. The time in seconds to assemble the project was noted, and the toy was disassembled out of the child's sight. Then the child was given the task to repeat. The researcher would conclude that learning occurred if the mean of the second assembly times was less than the mean of the first assembly times. At =α0.05, can it be concluded that learning took place? Use the...

In the journal Mental Retardation, an article reported the results of a peer tutoring program to help mildly mentally retarded children learn to read. In the experiment, the mildly retarded children were randomly divided into two groups: the experimental group received peer tutoring along with regular instruction, and the control group received regular instruction with no peer tutoring. There were n1 = n2 = 30 children in each group. The Gates-MacGintie Reading Test was given to both groups before instruction...

Cigarette Smoking A researcher found that a cigarette smoker smokes on average 31 cigarettes a day. She feels that this average is too high. She selected a random sample of 10 smokers and found that the mean number of cigarettes they smoked per day was 28. The sample standard deviation was 2.7. At a=0.05, is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the P-value method and tables. Compute the test value....

You may need to use the appropriate technology to answer this question. The College Board provided comparisons of Scholastic Aptitude Test (SAT) scores based on the highest level of education attained by the test taker's parents. A research hypothesis was that students whose parents had attained a higher level of education would on average score higher on the SAT. The overall mean SAT math score was 514.† SAT math scores for independent samples of students follow. The first sample shows...
