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!
Answer:
1/3
Step-by-step explanation:
for every 1 part of water there is 3 parts juice so if there's only 1 part juice it would be a 1/3
The correct statements are:
- the volume of the yellow candle is about 46.05 inches cubed.
- the radius of the yellow candle is 2 in
- he base area of the yellow candle is about 6.28 inches squared.
- the price of one yellow candle is about $16.12.
<h3>
What are the correct statements?</h3>
Volume of a cone = 1/3(πr²h)
- π = 3.14
- r = radius = diameter / 2 = 4/2 = 2 inches
- h = height
Volume of a cone = 1/3 x 2² x 11 x 3.14 = 46.05 inches cubed.
Base area = πr²
3.14 x 4 = 12.56 inches squared.
Price of one yellow candle = volume x price per cubic unit
46.05 x $0.35 = $16.12
