Just flip your fraction around and your answer will be 10/11
Answer:
less than 1, smaller than 1
Step-by-step explanation:
45-21=s
(the answer is 24 btw. you can check this by adding 24 and 21 to get 45 c:)
Answer:
The power of the test is 0.67.
Step-by-step explanation:
The complete question is:
A researcher is evaluating the influence of a treatment using a sample selected from a normally distributed population with a mean of μ = 80 and a standard deviation σ = 20. The researcher expects a 12-point treatment effect and plans to use a two-tailed hypothesis test with α = 0.05. Compute the power of the test if the researcher uses a sample of n = 16 individuals
.
Solution:
The information provided are:

The expected mean is:

The critical <em>z</em>-score at <em>α</em> = 0.05 for a two-tailed test is:
<em>z</em> = 1.96
*Use a <em>z-</em>table.
Compute the test statistic value as follows:

The power of statistical test is well-defined as the probability that we reject a false null hypothesis.
Power = Area to the right of the critical <em>z</em> under the assumption that H₀ is false.
Location of critical <em>z</em> (in H₀ is false distribution) = 
This is negative because the critical z score is to the left of the mean of the H₀ in false distribution.
Area above z = -0
.44.
Compute the value of P (Z > -0.44) as follows:

Thus, the power of the test is 0.67.
Answer:
A. 625 cubic units
Step-by-step explanation:
The formula to find the volume of the prism = Base area * height.
Here the base area of the prism is a square, which is given as 125 square units.
Height = 5 units
The volume of the prism = 125 *5
= 625 cubic units
Hope this will helpful.
Thank you.
