A researcher wanted to know if there was a difference in the effectiveness training results between permanent employees at a business and temporary employees at the same business.

QUESTION 16
A researcher wanted to see whether there was a difference
between NYC citizens and Boston citizens in the amount of time (in
hours) they spent outside during April 2020. He collected two
samples – one of NYC citizens and the other of Boston citizens, and
measured the amount of time each subject spent outside during April
2020. Sample #1 (of NYC citizens) contained 20 subjects
(n1=24), the mean number of hours spent outside was
M1=40, and the sample’s...

lifestyles were broken up into 3 groups: Diet 1, Diet 2, and Diet
3. Conduct an ANOVA on the following table with alpha = 0.5 to
determine if at least...
