Answer:
(a) = 7 +3·5
Step-by-step explanation:
The given expression evaluates to ...
6 +2^4 = 6 +16 = 22
The offered choices evaluate to ...
7 +3·5 = 7 +15 = 22
4·10^3 +96 = 4·1000 +96 = 4096
7^2 = 49
3·10 +2 = 30 +2 = 32
The only choice that will form a proper equation is the expression that evaluates to 22:
6 +2^4 = 7 +3·5

Answer:
Cohen's D
Step-by-step explanation:
Cohen's D is a statistic that measures effect size. It shows standardised difference between 2 means.
Effect size is defined as how large the effect of a something is or its magnitude.
Cohen's D works effectively when the sample is >50 (that is for large samples). However a correction factor can be used to make results from small samples more accurate
The formular for Cohen's D is:
D = (mean1 - mean2) ÷ (√({standard deviation1}^2 + {standard deviation 2}^2)/2)
This is the most appropriate method in the given scenario
