Example 2: Bryan coaches track and field at a local high school and during the previous season he got the impression that his 800m runners performed better when their races were in the morning as opposed to the afternoon. This season, he wanted to determine if his runners in fact performed better in the morning so he recorded all of their times for each race throughout the entire season. The data that he recorded for the morning and afternoon races are shown below. Carry out an appropriate hypothesis test at the a = 0.05 level to determine if his 800m runners performed better in the morning than in the afternoon. Sample Size Standard Deviation Average Morning 38 14 122 Afternoon 54 13 124
Which of the following is not one of the four steps of the hypothesis test? A. State the level of significance, choose a test, and check the conditions for the test B. Make a decision to reject or not reject the null hypothesis C. State the null and alternative hypothesis about the population parameter D. All of the these are steps of the hypothesis test
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. Do a minority of Michigan residents clear snow from sidewalks before 9 am after snow has fallen?For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________
Is the statement a valid null hypothesis? Ho : 19 = 7
What are the null and alternative hypotheses? A. H0: The two variables, x and y, are associated. Ha: The two variables, x and y, are not associated. B. H0: The variable x is dependent upon y. Ha: The variable y is dependent upon x. C. H0: The two variables, x and y, are not associated. Ha: The two variables, x and y, are associated. The P-value is (Round to three decimal places as needed.) What is the conclusion of the independence test? A. Do not reject H0. The data provide sufficient evidence of an association. B. Reject H0. The data provide sufficient evidence of an association. C. Do not reject H0. The data do not provide sufficient evidence of an association. D. Reject H0. The data do not provide sufficient evidence of an association.
Which of the following statements represents a null hypothesis? Strawberries are more nutritious than raspberries. More people prefer Burger King over McDonald's cheeseburgers. COVID is not more dangerous than influenza virus. Smoking cigars has a lower risk of cancer compared to smoking cigarettes.
Suppose that you are considering whether to publish a weekly alternative newspaper on campus. You decide to survey a random sample of students on your campus to ask if they would be likely to read such a newspaper. Your plan is to proceed with publication only if the sample data provide strong evidence that more than 10% of all students on your campus would be likely to read such a newspaper. The parameter of interest is the proportion of all students who would likely read an alternative campus newspaper. The null hypothesis = 0.10 and the alternative hypothesis is greater (>) than 0.10. -What is power in the context of this problem?
Can the null hypothesis be a greater than or less than or is it always equals?
Express the null hypothesis H and the alternative hypothesis Hin notation form in the following scenarios: The percentage of women who watches sports on TV is nor 40% as claimed by a researcher.
If the conclusion in a hypothesis test is to fail to reject H0H0, we can conclude that there is strong evidence that the null hypothesis is true.
