Answer:y=-3/5X-9
Step-by-step explanation:
use the formula y=mx+b and plug in your x, y and your slope (m), b is the unknown so you get everything to one side and b by itself so it’s -9 then you plug that all back in
Answer:
Rewrite the question correctly! it's totally absurd
We cant answer it cause we don't know all the statements
The z-value that corresponds to a two-tailed 95% confidence interval is z = +/- 1.96. Then the bounds of the confidence interval can be determined as:
Lower bound = mean - z*SD/sqrt(n) = 20 - 1.96*2/sqrt(100) = 20 - 0.12 = 19.88 hours
Upper bound = mean + z*SD/sqrt(n) = 20 + 1.96*2/sqrt(100) = 20 + 0.12 = 20.12 hours
So the first choice is the correct answer: 19.88-20.12 hours
