Answer:
a. z = 2.00
Step-by-step explanation:
Hello!
The study variable is "Points per game of a high school team"
The hypothesis is that the average score per game is greater than before, so the parameter to test is the population mean (μ)
The hypothesis is:
H₀: μ ≤ 99
H₁: μ > 99
α: 0.01
There is no information about the variable distribution, I'll apply the Central Limit Theorem and approximate the sample mean (X[bar]) to normal since whether you use a Z or t-test, you need your variable to be at least approximately normal. Considering the sample size (n=36) I'd rather use a Z-test than a t-test.
The statistic value under the null hypothesis is:
Z= X[bar] - μ = 101 - 99 = 2
σ/√n 6/√36
I don't have σ, but since this is an approximation I can use the value of S instead.
I hope it helps!
98 divided by 2 equals 49
55 divided by 5 equals 11
Answer:
The volume is 75
Step-by-step explanation:
because the volume is the width, length, and height, add them together.
Answer:
i believe it is -4 1/3 i may be wrong
Step-by-step explanation:
difficult, let me see....
1st slope:-4
2nd slope:4/6
3rd slope:-3
-2+4/7-3=-5+4/6=-4 2/6=
-4 1/3
