Answer:
78.46
Step-by-step explanation:
Given that
Pop. Standard deviation = 1.61
Sample standard deviation = 2.15
Sample mean = 7.47
Sample size = 45
Recall that
Test stat for chi square
= (n - 1) (sample standard dev/pop standard dev)^2
= 45 - 1 (2.15/1.61)^2
= 44(1.3354)^2
= 44 × 1.78329
= 78.46
