Midterm Part 2 – questions 4 to 6 include their answers (total questions is 16)

Use this information for the next four questions: Researchers wanted to know about a standardized test that was used across the country. To get an estimate of the answer, they collected data from two classrooms of students who completed the test.
Scores from Classroom A:
8, 6, 9, 9, 8, 7, 8, 9, 10, 8, 10, 5, 4, 10, 9, 9

Scores from Classroom B:
9, 8, 7, 8, 9, 10, 9, 10, 7, 8, 10, 9, 9, 4, 6, 3

4) The set of all scores on the standardized test across the country is:
Select one:
a. a statistic
b. a parameter
c. the sample Incorrect
d. the population…> Correction

6) What is the mean score in Group A?
Select one:
a. 8.4375
b. 8.3125
c. 8.0625…> Correct
d. 8.375
e. 8.4375 / sqrt(n)
R code:
> x <-c(8, 6, 9, 9, 8, 7, 8, 9, 10, 8, 10, 5, 4, 10, 9, 9)
> mean(x)
Result:
