Hi, I'm stuck with question 2. Question 1 given the example for this question
An analysis of restaurant rating is being undertaken. A sample of restaurants was selected and rating levels (one to five stars) were recorded along with other basic characteristics such as type of food (eg, French, Italian, Asian Fusion, Rotisserie Grill, etc.), average cost of a meal, location, seating capacity etc. The goal was to assess differences in ratings given to restaurants with various business - oriented covariates. Briefly discuss what type of model you would use and why.
A study was conducted using 50 mobile network users who volunteered to participate in a research as the entry of the third telco player in the country is on its way. One of the variables studied was the data connection speed in the previous month. Based on the data in the following table, is there a significant difference between the connectivity speeds of the two present mobile networks during the previous month? Use a 5% level of significance and assume that the population variances are equal. 1. The alternative hypothesis for the test would be? 2. The alternative hypothesis for the test would be? 3. What is the computed value of the test statistic? 4. What would be your decision?
Explain whether homogeneity of variance is satisfied for this analysis, and be clear on how you decided this.
Post-hoc tests are necessary for an analysis of variance comparing only two treatment conditions. t or f
Define ADL or GLS: Bias versus variance?
What correctly represents the coefficient of determination in terms of the variance that is an output from the analysis of variance table?

In a study performed on comfort food eating during times of stress, it was found that mean rated comfort food consumption level (on a scale from 1-20) for a group of students undertaking their exam period was 14. In comparison, a group of students who were not undertaking exams or examination preparation had a mean rated comfort food consumption level of 10. The pooled estimate of the population variance was 64. What is the estimated effect size (d) of the study? 0.80 0.06 0.50 2.00

The article cited in Exercise 19 provides measures of electrical conductivity (in uS/cm). The results are presented in the following table. Sample Size 49 Location Mean SD Upstream 463 208 Midstream 363 98 31 Downstream 647 878 30 Can a one-way analysis of variance be used to determine whether conductivity varies with location? Or is one of the necessary assumptions violated? Explain.
