es. An academician is curious to determine if the same pattern also exists in Kota Kinabalu. He randomly selects 320 non science graduates and 425 science graduates for the analysis. The following table contains the sample information:  a. Test if the proportion of unemployed non-science male graduates is 5 percent less than

Suppose that a middle school is using two different teaching formats for their 6th grade math classes: In-Person and Online. At the end of the school year the 6th grade students are given a test where their math skills are scored as Excellent, Proficient, Needs Improvement, or At-Risk. The middle school collects the following data: Excellent Proficient Needs Improvement At-Risk (a) What was the sample size in this study? In Person 39 75 59 18 Online 11 51 6 15 (b) What percentage of the sample were students that took an In-Person class AND scored Excellent on their test? (c) What percentage of the sample were students that took an Online class OR scored Needs Improvement on their test? (d) Construct the conditional distribution based on teaching format. Which teaching format had the HIGHEST rate of At Risk scores? What was that rate? (f) Use the conditional distribution to give a one or two sentence argument for why In-Person classes seem to be the more successful teaching format. (g)…

In 2015, Addison Group and Kelton surveyed the work preferences and attitudes of 1081 working adults spread over three generations-Baby Boomers, Generation X, and Millennials (Society for Human Resource Management website). One question asked individuals if they would leave their current job to make more money at another job. The file Millennials contains the sample data, which is also summarized in the following table. Click on the datafile logo to reference the data. DATA file Leave Job for More Money? Yes No Baby Boomer 137 213 Generation 7.85 What is the p-value? Use Table 3 of Appendix B. The p-value is between 0.005 and 0.01 Using a 0.05 level of significance, what is your conclusion? Conclude interest in leaving job for more money is not Generation X 171 199 Millennial 175 186 Conduct a test of independence to determine whether interest in leaving a current job for more money is independent of employee generation. Compute the value of the X² test statistic (to 2 decimals). Do…

In the Star and Tribune newspaper, there is an article entitled "1 in 8 school buses fail tests." The article says that the overall statewide proportion of school buses that fail safety tests is 9%. However, one bus company has a higher rate of over 12%. Assume that we want a new estimate for the statewide proportion of school buses that fail the safety inspection. We take a sample of 500 buses and find that 90 buses fail the safety inspection. Based on the new sample data, I construct this 90% confidence interval estimate for p: 152 < p < .208. Explain what this confidence interval means. O I am 90% sure that the number of buses that fail the inspection is between.152 and .208. O I am 95% sure that the true proportion of buses that fail the inspection is between .152 and .208. O I am 90% sure that the proportion of buses in this sample that fail the inspection is between .152 and .208. O I am 90% sure that the true proportion of buses that fail the inspection is between .152 and .208.
