(Problem for Questions 22- 25). In a study focusing on children on the autism spectrum a team of psychologists were interested in the distribution of the children on the spectrum. After having 100 children complete some tests, they categorized children as Low, Medium, High on the autism spectrum. They counted how many children were in each category and this is what they came up with: Low AS 44 Medium AS 30 High AS 26

For the following cases, you may use either the P-value approach or the rejection region approach to present a full hypothesis test, including: Identifying the claim and H0 and Ha, Finding the appropriate standardized test statistic, Finding the P-value or the rejection region, Deciding whether to reject or fail to reject the null hypothesis, and Interpreting the decision in the context of the original claim. A fitness magazine advertises that the mean monthly cost of joining a health club is less than $25. You work for a consumer advocacy group and are asked to test this claim. You find that a random sample of 18 clubs has a mean monthly cost of $26.25 and a standard deviation of $3.23. Perform the appropriate hypothesis test at α = 0.10.
A UW Madison professor is interested in learning about the variance of grades for university students. The professor gathers the sample variance for a random sample of 50 students. From past experience, the professor knows that the population of students is normally distributed. The sample variance that is collected is equal to 80. The professor would like to infer at the 1% significance level that the population variance is less than 100? - State the appropriate null and alternative hypothesis. - What is the correct test statistic? - What is the conclusion of the test? - What would be the effect if the professor increased the sample size?
A psychology graduate student wants to test the claim that there is a significant difference between the IQs of spouses. To test this claim, she measures the IQs of 9 married couples using a standard IQ test. The results of the IQ tests are listed in the following table. Using a 0.10 level of significance, test the claim that there is a significant difference between the IQs assuming that the population distribution of the paired differences is approximately normal. Let the spouse 1 group be Population 1 and let the spouse 2 group be Population 2. IQs of Married Couples Spouse 1 122 104 123 113 110 103 112 111 105 Spouse 2 120 108 126 114 112 105 117 110 110 State the null and alternative hypotheses for the test. Compute the value of the test statistic. Round your answer to three decimal places. Draw a conclusion and interpret the decision.
If you have do not have enough evidence to reject the null hypothesis at the 5% significance level using the critical value method, you will not have enough evidence to reject at the 10% significance level. True O False
A psychology graduate student wants to test the claim that there is a significant difference between the IQs of spouses. To test this claim, she measures the IQs of 9 married couples using a standard IQ test. The results of the IQ tests are listed in the following table. Using a 0.02 level of significance, test the claim that there is a significant difference between the IQs assuming that the population distribution of the paired differences is approximately normal. Let the spouse 1 group be Population 1 and let the spouse 2 group be Population 2.
