Is achieving a basic skill level related to the location of the school? The results of a random sample of students by the location of school and the number of students achieving basic skill levels in three subjects is shown in the contingency table. At a = 0.01, test the hypothesis that the variables are independent. Complete parts (a) through (d).

A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.

(c) Calculate the test statistic. d) Decide whether to reject or fail to reject the null hypothesis. Then interpret the decision in the context of the original claim.

When conducting a hypothesis test, we hope to avoid commiting a type 1 error, which is: 1. Not as bad as committing a type 2 error 2. rejecting a null hypothesis when it is true 3. rejecting the alternate hypothesis when it is true 4. accepting the null hypothesis when the alternate hypothesis is true

A researcher wants to test whether there is a difference in test scores between two groups. Which hypothesis should be the null hypothesis? a. There is a difference in test scores between the two groups. Ob. There is no difference in test scores between the two groups. Oc. The test scores of the two groups are positively related. Od. The test scores of the two groups are negatively related.

What calculator button would be used to perform a hypothesis test if the null and alternative hypothesis are as follows: Ho: P₁ = P2 H₁ P₁ P2 Select one: O a. Z-Test... O b. 2-SampZTest... O c. T-Test... O d. 2-SampTTest O e. 2-PropZTest...

(d) Decide whether to reject or fail to reject the null hypothesis. O A. Fail to reject H, because the test statistic is in the rejection region(s). O B. Reject H, because the test statistic is not in the rejection region(s). O C. Fail to reject Ho because the test statistic is not in the rejection region(s). D. Reject Ho because the test statistic is in the rejection region(s). (e) Interpret the decision in the context of the original claim. A. At the 5% level of significance, there is sufficient evidence to reject the claim that the mean price is $24,000. B. At the 5% level of significance, there is not sufficient evidence to reject the claim that the mean price is $24,000. C. At the 5% level of significance, there is sufficient evidence to reject the claim that the mean price is not $24,000. O D. At the 5% level of significance, there is not sufficient evidence to reject the claim that the mean price is not $24,000.

Suppose that you want to perform a hypothesis test for a population mean, μ. a. Express the null hypothesis both in words and in symbolic form. b. Express each of the three possible alternative hypotheses in words and in symbolic form.

When using the 4 step hypothesis testing method, the alternative hypothesis __________? a. is symbolized by: H1 b. is symbolized by: H0 c. states that the two population means are equal d. must be directional in nature (must be a one tailed test)

For the given hypothesis test, explain the meaning of the kind of error, as requested. A statistics student has heard that about 25% of the students on his campus attend sporting events weekly. He wants to know if statistics students attend events in the same proportions as the general student body. Explain what the second type of error would be in this case (where the student fails to reject a null hypothesis that is actually false). O A. The second kind of error would be saying that statistics students attend sporting events in much higher proportions than the student body as a whole, even though they actually have the same attendence proportion. B. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at sporting events, even though there really is. O C. The second kind of error would be saying that there is no difference in the attendence of statistics students and the student body as a whole at…
