1. Researchers are interested in whether the average time spent on a phones varies by region and age group. They gather information from four different regions and five different age groups (Under 18, 18-29, 30-45, 46-64, 65+). With data from 50 respondents, they create the following ANOVA table.
   1. Complete the ANOVA table below by filling in the shaded boxes
   2. Find the appropriate critical value(s) [ ]
   3. Does cell phone screen time vary significantly with region, age group, or their interaction? Clearly answer for each.

5. School district officials are curious if test scores vary across the four high schools in their district. They gather standardized test scores from students at these 4 schools. The variables in the dataset are as follows:

School: Which school the student attends

Score: Score on standardized test

For the Excel data, the data are organized with each column containing the test scores for a single school.

Using either ps11_school.xlsx or ps11_school.sav, test whether test score significantly differs across schools ( ). Include program output for the problem in addition to your answer.
