A tutorial school has been running IELTS mock examination for many years. Below is the summary presented by the tutorial school related to the IELTS mock examination in one of the many online classes selected randomly in year 2022. IELTS score in mock examination Number of students < 4 5 2 5 7 15 8 10 9 3 A report presented by this tutorial school 5 years ago indicated that the population mean score of IELTS mock examination was 7.05 points and the population proportion of students got 7 points or above was 0.67. (a) Construct a 95% confidence interval estimate of population mean score a student get in the IELTS mock examination in 2022. (b) Test, at 1% level of significance, if the population proportion of students get 7 points or above in 2022 is higher than that in year 2017. (The report must include the (i) null hypothesis and alternative hypothesis, (ii) rejection region(s), (iii) calculation of test statistics, and (iv) conclusion.)

Design a two-factor ANOVA with variables of interest (personal, academic, career). In addition state your 3 hypothesis (2 main effects, 1 interaction). Example: Two-Factor ANOVA to evaluate the effect of Video Game Violence and Grade on Aggression Factors1. Factor A: Video Game Violence level (3 levels: low, moderate, high) 2. Factor B: Grade level (4 levels: 1st grade, 2nd grade, 3rd grade, 4th grade) 3. Dependent Variable: Aggression Hypothesis Tests1. Video Game Violence level affects Aggression2. Grade level affects Aggression 3. Interaction between Video Game Violence level and Grade level: video game violence level will affect aggression but only for 3rd and 4th graders but not for 1st and 2nd graders.

A regional planner obtains random samples of home costs from four Michigan counties. Suppose these home costs are normally distributed in each county and that home prices within each county vary about the same amount. What test should the planner use to learn if the differences in home cost by county are significant? State the null and alternative hypothesis Provide the name of the hypothesis testing method and explain why it is appropriate.
The hypothesis test result only tells us whether there is a significant difference between 2 populations or not. Calculate the exact standardized effect size using the provided information.
On a trial basis, State College admitted 300 students from the lowest third of their high school graduation class. They were randomly divided into 3 groups. Group A received extensive training in study habits Group B received motivational lectures; and Group C received no special treatment. At the end of the year, the average grades of the groups were compared. Identify the following: * What is the Independent variable? * What is the Dependent variable? * Who is in the Experimental Group? * Who is in the Control Group? * What are at least 2 potential extraneous variables?

According to areport on consumer fraud and identity theft, 22% of all complaints during one year were for identity theft. In that year, Michigan had 322 complaints of identity theft out of 1457 consumer complaints.
