For a statistics project a community college student at Diablo Valley College decides to investigate cheating in two popular majors at DVC: business and nursing. She selects a random sample of nursing and business courses and convinces the professors to distribute a short anonymous survey in their classes. The question about cheating is one of many other questions about college life.

When the student summarizes the data, she finds that 42 of the 50 business students and 38 of the 70 nursing students admitted to cheating in their courses. Can the student proceed with the calculation of the confidence interval for the difference in population proportions?

Answers

Answer 1

Answer:

The student can proceed with the calculation of the confidence interval for the difference in population proportions. This is because, from the data she has, 3/4 of the Business students admitted to cheating while 1/2 of the Nursing students admitted to cheating also.

This is above the average number of students in her given sample size which is valid for extrapolation to the College Majors being investigated.

Answer:

33.72

Step-by-step explanation:

To figure out the answer, we need to find the total area of the rectangle, and then subtract the blank shape.

Lets first find the area of the rectangle. 4x10=40

Lets now find the area of the blank shape. We fill caculate the area of the circle and then divide by 2 because it is a half circle. 4/2=2. 2x2=4. 4x3.14= 12.56/2=6.28

40-6.28= 33.72

Solve 6y + 2x = 14 for x.

X= 7-3y

X has to be on one side

6y+2x =14
2x= 14-6y
X= 7-3y

Now we can plug that into the original equation (check)

6y + 2(7-3y)
6y+ 14-6y
14=14

X= 7-3y

Do these ratios make a proportion? 4:10 and 6:15

I NEED THIS ASAP!!! Thanks!

Answers

To see if these ratios make a proportion let us first change them into fractions

= 4:10 = 4/10 = 4 ÷ 2 / 10 ÷ 2 = 2/5

= 6:15 = 6/15 = 6 ÷ 3 / 15 ÷ 3 = 2/5

= Since both these ratios are getting simplified into a same fraction , they are proportional .

Therefore , 4 : 10 :: 6 : 15 ( 4 : 10 is proportional to 6 : 15 )
