The designers of a standardized test are interested in knowing how long people take, on average, to complete the writing portion of the test. They decide to conduct an observation study at a testing facility. To avoid bias in their study, they create a list of the test takers scheduled to take the test this week. Then, they randomly select 50 test takers from the list to be part of the study.
In this situation, what does the list of test takers represent?
A. the frame
B. the population
C. a control group
D. a sample
Answers
Answer:
A. Frame
Step-by-step explanation:
This is because it does not contain the who population and it is the place where the participants of the experiment are selected. It is not the control group because this includes people who were not even in the experiment.
The list of test takers represent the frame.
A frame consist of everyone in the population that has a chance of being picked.
The population represents the individuals that the researchers is interested in conducting the research on. The population of a study has similar characters.
The sample is the person that's selected from the population and represents the population as a whole.
The control group refers to the people that didn't partake in the experimentation carried out.
Therefore, the 50 test takers from the list represents the frame.
In conclusion, the correct option is A "frame".

A 1948 study in Biometrika investigated the effects of several different diets on the weight of chickens. In this study, chickens were randomly assigned to one of several different groups, and each group of chickens received a different type of feed. The data provided represent a subset of data from this study and show the weights (in grams) of chickens receiving the sunflower, meatmeal, soybean, and casein feeds.
Use software to conduct an analysis of variance (ANOVA) ????F‑test to test the claim that the mean weights of chickens receiving sunflower, meatmeal, soybean, and casein are equal. What are the ????F‑statistic and pp‑value for this test? Please round your ????F‑statistic to the nearest two decimal places and your pp‑value to the nearest five decimal places.
1. ????F‑statistic :
2. pp‑value :
Based on the pp‑value for this ANOVA ????F‑test, select the correct conclusion at the ????=0.05α=0.05 level.
a. Since the pp‑value is greater than ????=0.05α=0.05, there is little evidence of a difference in the mean weights of chickens receiving the sunflower, meatmeal, soybean, and casein feeds.
b. Since the pp‑value is less than ????=0.05α=0.05, there is significant evidence of a difference in the mean weights of chickens receiving the sunflower, meatmeal, soybean, and casein feeds.
c. Since the pp‑value is less than ????=0.05α=0.05, there is little evidence of a difference in the mean weights of chickens receiving the sunflower, meatmeal, soybean, and casein feeds.
d. Since the pp‑value is greater than ????=0.05α=0.05, there is significant evidence of a difference in the mean weights of chickens receiving the sunflower, meatmeal, soybean, and casein feeds.

Evaluate the expression
Answers
Answer:
39
Step-by-step explanation:
6a - b = 6 x 8 - 9 = 48 - 9 = 39
Answer: 39
Step-by-step explanation:
Given that a=8 and b=9
The expression is 6a-b
That is; we have to find 6 times a and then subtract b from it.
6a = 6*8=48
b=9
6a-b=48-9=39
Therefore the answer to the question is 39.
Use compositions to determine if the functions below are inverses of
each other?*
f(x) = 5x & F-1(x) = x
Yes
No
Answers
Answer:
They are not inverse functions
Step-by-step explanation:
Given
[tex]f(x) = 5x[/tex]
[tex]f^{-1}(x) = x[/tex]
Required
Determine if both are inverse functions
First calculate the inverse of f(x)
[tex]f(x) = 5x[/tex]
Replace f(x) with y
[tex]y = 5x[/tex]
Swap x and y
[tex]x = 5y[/tex]
Make y the subject
[tex]y = \frac{1}{5}x[/tex]
Replace y with f-1(x)
[tex]f^{-1}(x) = \frac{1}{5}x[/tex]
By comparison:
[tex]f^{-1}(x) = x[/tex] and [tex]f^{-1}(x) = \frac{1}{5}x[/tex] are not the same:
Hence:
[tex]f(x) = 5x[/tex] and [tex]f^{-1}(x) = x[/tex] are not inverse functions

Required:
Volume of sphere
Solution:
V = ⁴/3πr³
Plug in the values
V = ⁴/3 * 3 * 3³
V = ⁴/3 * 3 * 27

Let |r| = 6 at an angle of 30° and |s| = 11 at an angle of 225°. Which expression represents |r – s|?
Answers
The resultant of subtraction of both vectors is
|r - s| = √(r² + s² - 2rscos{15})
What are vectors?A vector is an object that has both a magnitude and a direction.
Given is that |r| = 6 at an angle of 30° and |s| = 11 at an angle of 225°.
For the subtraction of vectors, we can write its magnitude as -
|r - s| = √(r² + s² - 2rscos{15})
Therefore, the resultant of subtraction of both vectors is
|r - s| = √(r² + s² - 2rscos{15})
