Researchers were investigating whether there is a significant difference between two medications, R and S, designed to reduce fleas found on cats. From a sample of 300 cat owners, the researchers randomly assigned 150 cat owners to use medication R on their cats and the remaining cat owners to use medication S. For the cats using medication R, 88 percent had no fleas. For the cats using medication S, 90 percent had no fleas. Which of the following is the most appropriate method for analyzing the results?
A two-sample z -test for a difference in population proportions
A two-sample z-test for a difference in sample proportions
A one-sample z-test for a sample proportion
A one-sample z-test for a population proportion
A one-sample z-test for a difference in sample proportions
Answer:
A) A two-sample z -test for a difference in population proportions
Step-by-step explanation:
To determine whether a difference in proportions is significant, the two-sample z-test for a difference in population proportions is the most appropriate method for the analysis.
The most appropriate method for analyzing the results is A. A two-sample z-test for a difference in population proportions.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter.
In this scenario, we have two different treatments (medication R and S) applied to two separate samples (150 cat owners each) and we want to determine if there is a significant difference in the proportion of cats with no fleas between the two groups.
This is a classic scenario for a two-sample z-test for a difference in population proportions, which tests the hypothesis that the difference in proportions between two independent populations is equal to zero.
Thus, a two-sample z-test for a difference in population proportions.
Hence, the correct answer would be option (A)

Write the equation of each line in slope-intercept form and identify the slope. 4x=2+y
Answer:
y = 4x - 2
Step-by-step explanation:
Given: 4x=2+y
First, subtract 2 on both sides to isolate out y. (Slope-intercept form is y=mx+b)
Once subtracted, you get: 4x-2=y
Rearrange it, and you get: y=4x-2
Find it ! Find the perimeter
Answer:
P=60
Step-by-step explanation:
P=2(l+w)
P=2(14+16)
P=2(30)
P=60
Perimeter of a rectangle with 16in length and 14in width is 60 in.
Perimeter of a rectangle = 2(l+b)
here l = length and b= width
Given : l= 16 in and b= 14 in
perimeter = 2(l+b)
= 2(16+14)
= 2(30)
=60 inches.
The perimeter of rectangle is 60 inches

what is the side length of a square given the area to be 625m
Answer: 25 meters
Step-by-step explanation:
✓625 = 25
Answer:25
Step-by-step explanation:A square has equal length on all its sides, so the area of square is
Length x Length = 625
Which is
Length ^2 = 625
We want the number that when it times it’s self it’s 625
It can be done by square root of 625 which is 25. So the length of side is 25.
Or look at the prime factorization of 625 ( or just factors) and what number they can make up
Which is 5x5x5x5 = 625
They can make up
5^2 x 5^2 = 25 x 25 that is the “same” number
So the length is 25

The probability of rolling a 2 on a number cube is 1/6 . If you were to roll the
cube 30 times, you would expect to get a 2 around 5 times (1/6 · 30 = 5).
You simulate 30 rolls. How many 2s would make you question your model?
A. 14
B. 5
C. 2.
D. 8
Answer: a
Step-by-step explanation:
If a cube is rolled by 30 times then 5 times 2s will make the question the model.
What is probability?Probability is the occurrence of any event or how likely an event can happen.
Mathematically probability = the number of desired outputs by the number of the possible outcomes.
In the number cube, there are six faces above each of them written one to six later.
The probability of getting 2 at once time will be 1/6 since the number of desired output is only one and possible outcomes are six.
Mathematically(Theoretically) if we roll the cube 30 times then the number of 2s will be 1/6 × 30 = 5 times.
If experimentally if we roll dice and the number of 2s came 5 times then our question will become a model.
So by 5 times, 2s will make the question model.
