“About Us” Survey. Test hypothesis to check the claim that gender doesn’t create any difference in heart rates between young males and females. Use the significance level  = 0.01 .
Use two random samples taken from survey data and computer output provided.

Don’t need to calculate the standard error by hand, use SEx1 −x2 = 4.51

  1. Fill out the table

  2. Write appropriate null and alternative hypotheses.

  3. Perform the test.

  4. Estimate and interpret the p-value.

  5. Sketch the distribution curve to show the value of test statistics and p-value of the test.

  

Females

Males

n= 1

n2 =

x= 1

x2 =

s1 =

s2 =

  1. Based on the p-value, what is your decision?

  2. Explain your conclusion in the context of the problem.

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. A study was done on body temperatures of men and women. Here are the sample statistics for the men: x1 = 97.55oF, s1 = 0.83oF, n1 = 11, and for the women: x2 = 97.31oF, s2 = 0.65oF, n2 = 59. Use a 0.06 significance level to test the claim that µ1 > µ2.

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, Form 2 of the Gates-MacGintie Reading Test was administered to both an experimental group and a control group after 6 weeks of instruction, during which the experimental group received peer tutoring and the control group did not. For the experimental group n1 = 30 children, the mean score on the vocabulary portion of...
