Answer:

Step-by-step explanation:
stupid enough
y=mx+b

slope = 16-12/3-6
-4/3

plug in x and y
16=-4/3(3)+b
b=20

Answer: y = 3
Step-by-step explanation:
Answer:
0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
Step-by-step explanation:
The following information is missing:
The standard deviation of population is 100.
We are given the following information in the question:
Population mean, μ = 502
Standard Deviation, σ = 100
Sample size, n = 90
Standard error =

Formula:

P(test score within 10 points)


0.658 is the probability that a sample 90 test takers will provide a sample mean test score within 10 points of the population mean of 502.
