Answer:
Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .
Step-by-step explanation:
Given that a research report describing the results from a repeated-measures study states:
The data show no significant difference between the two treatments, t(10) = 1.65, p > .05.
Since t(10) is given, we can conclude that degrees of freedo is 10
Hence sample size is 10+1 =11
Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .
The correct two-way frequency table for the date will look like this:
RAP ROCK COUNTRY TOTAL
Grades 9-10 40 30 55 125
Grades 11-12 60 25 35 120
TOTAL 100 55 90 245
The sum of the row total is equal to the sum of the column total
125 + 120 = 100 + 55 + 90
245 = 245
