A 95 percent confidence interval for the proportion difference p1−p2 was calculated to be (−0. 12,0. 17). Which of the following

conclusions is supported by the interval?
SAT
1 answer:
Alla [95]2 years ago

The only conclusion that is supported by the interval is; C. There is evidence to conclude that p1>p2 because all values in the interval are positive.

<h3>What is the confidence Interval?</h3>

We are given a confidence interval for the difference in proportions. The null hypothesis means that there's no difference. Thus;

H0 = p1 - p2 = 0

However, If the difference is positive, it means that we have sufficient evidence as p1 > p2 but If it's negative, then we have sufficient evidence as p2 > p1.

Option A: This is incorrect because of interpretation of the interval.

Option B & D: They are not correct because they are incomplete

Option E: This is not correct because it did not properly get the definition of alpha-level and p-value with confidence interval values.

Thus, only option C is correct.

The missing options are;

A. There is evidence to conclude that p1>p2 because 0.325 is greater than 0.247.

B. There is evidence to conclude that p1

C. There is evidence to conclude that p1>p2 because all values in the interval are positive.

D. There is evidence to conclude that p1

E. There is evidence to conclude that p2>p1 because 0.247 and 0.325 are both greater than 0.05.

1) What percent of 440 is 369?
zimovet [89]

Answer:

119.24

Explanation:

Step 1: We make the assumption that 369 is 100% since it is our output value.

Step 2: We next represent the value we seek with x​.

Step 3: From step 1, it follows that 100%=36​.

Step 4: In the same vein, x% = 440​.

Step 5: This gives us a pair of simple equations:100%=369(1) 440(2) = x%

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS(left hand side) of both equations have the same unit (%); we have 100%/x% = 369/440

Step 7: Taking the inverse (or reciprocal) of both sides yields x%/100% = 440/369

Therefore, 440​ is 119.24% of 369.

Lunna [17]

Answer:

PART A

  • Red: 7/29
  • Blue: 8/29
  • Yellow: 5/29
  • Green: 9/29

PART B

  • Red or blue: 7/29 + 8/29 = 15/29
  • Yellow or green: 5/29 + 9/29 = 14/29
  • Blue or yellow or green: 8/29 + 5/29 + 9/29 = 22/29

Explanation:

In this case where the question is asking or <u>OR</u> and the events are <u>mutually exclusive</u> (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red <u>OR</u> Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)

svet-max [94.6K]

A black and white scene showing men on horseback and men standing in a field. this print, created by picasso, displays a bold, highly contrasting design, which is characteristic of wood engraving.

Engraving begins by using a sharp, hand-held cutting device called a chisel to draw a design directly onto a metal plate. The tip of the chisel is sharp and pointed. The technique of wood engraving has been used for centuries to reproduce drawings and paintings.

This allowed more people to own or see the artwork of artists who would otherwise only have the original, eliminating the possibility of additional "copies" of their own images. By the 19th century, it was largely abandoned in favor of etching.

Picasso's use of chisels was always unorthodox, but he and other artists used chisels to create sharp, crisp lines on his plates that were etched into the printed image. converted evenly.

The correct answer is option B.
