Researchers examined the influence of a television program on children's aggressiveness. The number of aggressive responses was measured during an observation period after viewing the television program. Imagine that the known national average for number of aggressive responses typically performed by children who do not watch television is 6.847. Use the data below to conduct an analysis to determine if the number of aggressive responses on average is different from the national average.
Number of aggressive responses: 10, 5, 10, 11, 12, 6, 11
A) Is the assumption(s) met? Please explain your answer and proceed with the analysis even if the assumption(s) is not met.
B)What do you conclude from your analysis?
When the data has extreme scores, what is the best measure of average?
What are two variables that will be can be used in a chi-square analysis based in social work?
What would the best attributes be for each variable?

- An MBA student wants to answer the question "How does an MBA major affect the number of job offers received?" He randomly sampled four recent graduates in each of the following three MBA majors [Finance (x1), Marketing(x2) and Management(x3)] and asked each of them to report the number of job offers. He obtains the following results. Sum of square between majors (SSB) = 62.17 Mean of square within majors (MSW) = 2.28 Mean number of job offers received from each MBA major are as follows: Finance major (x1) = 2.25 Marketing major (x2) = 3.25 Management major (x3) = 7.5 Construct the Analysis of Variance (ANOVA) table, and then find the SSW 62.17 20.52 82.69 SST 20.52 62.17 82.69 MSB 31.085 50 2.28 F calculated 15.45 12.20 13.36arrow_forwardA community college professor is interested in determining the relationship between the number of posts students make on Schoology and their respective grades.

- The National Center for Health Statistics reports that the average systolic blood pressure for males 35-44 years of age has a mean of 121. The medical director of a large company believes the average systolic blood pressure for male executives 35-44 years of age at his company is different from 121. He asks for male executives aged 35-44 to volunteer to participate in his study. He looks at the medical records of the 81 volunteers and finds that the mean systolic blood pressure in this sample is 127.2 with a standard deviation of 28. Assume the population distribution is approximately normal. Conduct a hypothesis test at the 0.05 significance level to test this claim. What is the null hypothesis? What is the alternative hypothesis? What is the significance level? What is the value of the test statistic? Report your answer to two decimal places. What is the p-value?
