Answer:
G
Step-by-step explanation:
First off, we know that Trinity is allowed to watch 420 minutes of television a week, which means that her watch time can be=420, cannot be >than 420 minutes, and can be <than 420 minutes. (in other words, her watch time can be equal to or less than 420 minutes) Because of this, we know that our answer choice must have 420≥. So H and J are out of the question.
Also, we know that each show that she watches is 30 minutes long. Because of this, the next part of our answer is going to be 30s. (I will explain this in the comment section of my post because it's getting a little long)
Therefore, the answer is G: 30s≤420
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
