In a study, a random sample of 2625 US adults were asked whether they agree or disagree that there is "only one true love for ea

ch person." The response and gender of the participants is shown in Table 1.
Male Female Total

Agree 372 363 735

Disagree 807 1005 1812

Don't know 34 44 78

Total 1213 1412 2625


Table 1 Is there only one true love for each person?


(a) Use the information in the table to construct a confidence interval for the difference in the proportion who agree, between males and females, using the fact that the standard error for the difference is .


Round your answers to three decimal places.


The 95% confidence interval is

to

.


(b) Is it plausible that there is no difference between males and females in the proportion who agree that each person has only one true love?

Identify the lower class​ limits, upper class​ limits, class​ width, class​ midpoints, and class boundaries for the given freque
maw [93]

Answer:

The number of individuals included in the summary is 146.

Step-by-step explanation:

The frequency distribution table provided is as follows:

Class Intervals    Frequency

    100 - 199               24

   200 - 299              90

   300 - 399              27

   400 - 499                1

   500 - 599               4

The lower class limit it the smallest value of each class interval.

Lower class limit = {100, 200, 300, 400, 500}

The upper class limit it the highest value of each class interval.

Upper class limit = {199, 299, 399, 499, 599}

The lower class boundaries are the lower class limits decreased by 0.5 and the upper class boundaries are the upper class limits increased by 0.5.

Class boundaries:

   99.5 - 199.5  

  199.5 - 299.5

  299.5 - 399.5

  399.5 - 499.5

  499.5 - 599.5

The class width is the difference between the class boundaries of each class.

Class width = 199.5 - 99.5 = 100

So, the class width is 100.

The midpoints of a class is the average value of the boundaries of a class.

\text{Midpoint}_{100-199}=\frac{\text{Lower class boundary} + \text{Upper class boundary}}{2}\\

                         =\frac{99.5+199.5}{2}\\\\=149.5

\text{Midpoint}_{200-299}=\frac{\text{Lower class boundary} + \text{Upper class boundary}}{2}\\

                         =\frac{199.5+299.5}{2}\\\\=249.5

\text{Midpoint}_{300-399}=\frac{\text{Lower class boundary} + \text{Upper class boundary}}{2}\\

                         =\frac{299.5+399.5}{2}\\\\=349.5

\text{Midpoint}_{400-499}=\frac{\text{Lower class boundary} + \text{Upper class boundary}}{2}\\

                         =\frac{399.5+499.5}{2}\\\\=449.5

\text{Midpoint}_{500-599}=\frac{\text{Lower class boundary} + \text{Upper class boundary}}{2}\\

                         =\frac{499.5+599.5}{2}\\\\=549.5

The number of individuals included in the summary is the sum of all frequencies.

\text{Number of Individuals}=24 + 90 + 27 + 1 + 4=146

Thus, the number of individuals included in the summary is 146.

Someone please answer this, ill give you brainliest and your getting 100 points.
Alborosie

Answer:

Step-by-step explanation:

The answer is (B), because the rate of the function is 0.50 from 0 to 8 ounces, thus the line should have a slope of 1/2. But afterward, it levels off horizontally as every ounce above 8 ounces to 12 ounces is $4.

Hope that helps!

4 red bricks have a mean weight of 5kg
Elina [12.6K]

Answer: Donna is wrong. Mean weight is 7.1kg

Step-by-step explanation:

Calculate the mean for the bricks:

4 bricks have a mean weight of 5kg = 4 * 5

5 bricks have a mean weight of 9kg = 5 * 9

1 green brick is 6kg

= (4 * 5 ) + ( 5 * 9) + 6

= 71kg

Mean = 71 / (4 + 5 + 1)

= 7.1 kg
