The Consumer Reports National Research Center conducted a telephone survey of 2,000 adults to learn about the major economic concerns for the future. The survey results showed that 1,740 of the respondents think the future health of Social Security is a major economic concern.
Required:
a. What is the point estimate of the population proportion of adults who think the future health of Social Security is a major economic concern.
b. At 90% confidence, what is the margin of error?
c. Develop a 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern.
d. Develop a 95% confidence interval for this population proportion.
Answer:
a. 0.87
b. The margin of error is of 0.0124.
c. The 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern is (0.8576, 0.8824).
d. The 95% confidence interval for this population proportion is (0.8553, 0.8847).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The confidence interval is:
[tex]\pi \pm M[/tex]
a. What is the point estimate of the population proportion of adults who think the future health of Social Security is a major economic concern.
The sample proportion, that is, 1740 out of n = 2000. So
[tex]\pi = \frac{1740}{2000} = 0.87[/tex]
0.87 is the point estimate.
b. At 90% confidence, what is the margin of error?
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
Then the margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.645\sqrt{\frac{0.87*0.13}{2000}}[/tex]
[tex]M = 0.0124[/tex]
The margin of error is of 0.0124.
c. Develop a 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern
[tex]\pi - M = 0.87 - 0.0124 = 0.8576[/tex]
[tex]\pi + M = 0.87 + 0.0124 = 0.8824[/tex]
The 90% confidence interval for the population proportion of adults who think the future health of Social Security is a major economic concern is (0.8576, 0.8824).
d.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Then the margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.96\sqrt{\frac{0.87*0.13}{2000}}[/tex]
[tex]M = 0.0147[/tex]
The confidence interval will be of:
[tex]\pi - M = 0.87 - 0.0147 = 0.8553[/tex]
[tex]\pi + M = 0.87 + 0.0147 = 0.8847[/tex]
The 95% confidence interval for this population proportion is (0.8553, 0.8847).

2. Maggie can be made in 2 minutes. Pasta require at least 10 to 15 minutes.
3. Maggie is generally accompanied with veggies. Pasta is accompanied with sauses.
4. Maggie stick together like pudding in the lunch box. Pasta is unaffected.

The point graphed on the coordinate plane is either (3,8) or (8,8), depending on whether the horizontal axis is labeled from left to right or right to left.
What is graph?A graph is a visual representation of data or a mathematical equation. It is used to show the relationship between two or more variables, usually depicted on the horizontal and vertical axes of the graph.
The given points are of the form (x,y), where x is the horizontal axis coordinate (also known as the x-axis) and y is the vertical axis coordinate (also called the y-axis).
Each point in the given options is represented by its (x,y) coordinates. Based on the options provided, we must determine which point is graphed on the coordinate plane.
So, to accomplish this, we simply compare the (x,y) coordinates of each option to the coordinates on the graph and select the option that matches.
Thus, (3,8) or (8,8) can be the coordinate plane.

People who experience online harassment either ignore it or respond via postings or involving authorities Is one method more effective than the other? A 2014 Pew Research Center report, based on a random sample of American adults, found that 412 of the 549 respondents who had chosen to ignore online harassment thought that it was an effective way to deal with the issue. Of the 368 respondents who had chosen to respond to online harassment, 305 thought that it had been effective A.
Required:
a. Is there good evidence that one approach is more likely to be effective than the other? State the null and alternative hypotheses, obtain the test statistic and P-value, and conclude in context.
b. How large is the difference? Obtain and interpret in context a 95% confidence interval for the difference between the proportions of American adults who find ignoring online harassment effective and those who find responding to it effective.
c. How effective is that best method? Obtain and interpret in context a 95% confidence interval for theproportion of American adults who find the best m ethod effective.
Answer:
Step-by-step explanation:
First method information:
Sample size n₁ = 549
x₁ ( people ignoring on-line harassment ) = 412
Proportion of people ignoring on-line harassment p₁
p₁ = 412/549 p₁ = 0,75 q₁ = 1 - p₁ q₁ = 0,25
Second method ( people chosen to respond)
Sample size n₂ = 368
number of people responding x₂ = 305
Proportion of people responding
p₂ = 305/ 368 p₂ = 0,83 then q₂ = 0,17
a) Looking for differences in the approachs
Hypothesis test:
Null Hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₁ ≠ p₂
Alternative Hypothesis indicates that the test is a two-tail test
Choosing a confidence interval CI = 95 % then a significance level is α = 5% α = 0,05 and from z-table we get z(c) = 1.64
To calculate z(s)
z(s) = ( p₁ - p₂ ) / EED
EED = √ p₁*q₁)/n₁ + (p₂*q₂)n₂
EED = √ (0,75*0,25)/549 + 0,83*0,17)/368
EED = √ 3,41 *10⁻⁴ + 3,83*10⁻⁴
EED = 10⁻² *√ 3,41 + 3,83
EED = 10⁻² * 2,69
EED = 0,0269
z(s) = ( p₁ - p₂ )/0,0269
z(s) = - 0,08 / 0,0269
z(s) = - 2,97
p-value for z(s) is pvalue = 0,0015
Comparing z(s) and z(c) modules
z(s) > z(c) therefor z(s) is in the rejection region we have to reject H₀ and claim that there is a difference between the proportions
b) How large is the difference

A spinner has 4 blue sections, 6 red sections and 2 green sections. It is spun 24 times. For numbers 2a. – 2c., circle YES or NO to indicate whether you would expect the spinner to land on the given color the number of times stated.
Answer:
Blue = YES
Red = NO
Green = YES
Step-by-step explanation:
Given the distribution of colors on a spinner :
Blue = 4 ; Red = 6 ; Green = 2
Number of spins = 24
Total = (4 + 6 + 2) = 12
Recall:
Probability, P = required outcome / Total possible outcomes
P(red) = 6 /12 = 1/2
P(blue) = 4 / 12 = 1/3
P(green) = 2 / 12 = 1/6
On 24 spins :
Possible number of red = 1/2 * 24 = 12
Possible number of green = 1/6 * 24 = 4
Possible number of blue = 1/3 * 24 = 8

Answer:
21 yards
Step-by-step explanation:
The area of a quadrilateral with diagonals that are right angles to each other is given by ...
A = (d1)(d2)/2 . . . . where d1 and d2 are the lengths of the diagonals
493.5 yd² = (47 yd)(BD)/2 . . . . . . . . . . fill in the given information
