Answer:
p = 0.0116
Step-by-step explanation:
We are given;
Population mean; μ = 200 mg
Sample mean; x¯ = 194.3 mg
Standard deviation; σ = 21 mg
Sample size; n = 70
Formula for z-score is;
z = (x¯ - μ)/(σ/(√n))
z = (194.3 - 200)/(21/√70)
z = -5.7/2.51
z = -2.27
From the z-score table attached, the p-value at z = -2.27 is p = 0.0116

Dear Foxqueen, the dependent variable is D because the grades depend on the time spent playing video games. A is not logical because the video games owned might not be played, B is illogical because the points are the product of the video games, and C is not logical because that is actually the independent variable.
