Just as you are about to estimate a regression (due tomorrow), massive sunspots cause magnetic interference that ruins all electrically powered machines (e.g., computers). Instead of giving up and flunking, you decide to calculate estimates from your data (on per capita income in thousands of U.S. dollars as a function of the percent of the labor force in agriculture in 10 developed countries) using methods like those used in Section 2.1 (Yi = B0 + B1Xi + Ei) without using a computer. Your data are:Country A B C D E F G H I JPer Capita Income 6 8 8 7 7 12 9 8 9 10% in Agriculture 9 10 8 7 10 4 5 5 6 7a.) Calculate Beta-hat zero and Beta-hat one.b.) Calculate R2(r-squared) and R`2 (adjusted r-squared).c.) If the percent of the labor force in agriculture in another developed country was 8 percent, what level of per capita income (in thousands of U.S. dollars) would you guess that country had?

Answers

Answer 1

Answer:

A) Beta-hat one = -0.547

   Beta-hat zero = 12.2837

b) attached

C) y = $7.904

Step-by-step explanation:

hello attached below is the detailed solution and the table

A) Calculate Beta-hat Zero and Beta-hat one

Beta-hat one :

∑ ( xi - x ) (yi - y ) / ∑ (xi - x )^2

= -22.4 / 40.9 = -0.547

Beta-hat zero :

Y - Beta-hat one * X

= 8.4 - (-0.547 )(7.1 )  = 12.2837

B) Calculate R^2 and R^2

attached below

C) using Regression equalia to determine the level of per capita income

y = 12.28 - 0.547 * x

where x = 8

hence Y = $7.904

The volume πr^2*height/3=1471

π*r^2=1471/9*3

r= sqrt 156.16=about 12.5

A recent study was conducted in which a random sample of men and a random sample of women were surveyed about whether they were fans of a professional football team. The study found that 39 percent of men in the sample were fans and 22 percent of women in the sample were fans. A 99 percent confidence interval for the difference in the proportion of fans of a professional football team between men and women was reported as (0.133,0.207) . Which of the following statements is the best interpretation of the interval?

a. The difference in the percents of fans of a professional football team between men and women is 17%.
b. There is a 99% chance of finding a difference between 13.3% and 20.7% for the percents of men and women who are fans of a professional football team.
c. We are 99% confident that the percent of men who are fans of a professional football team exceeds that of women by at least 20.7%.
d. We are 99% confident that the difference in the sample percents of men and women who are fans of a professional football team is between 13.3% and 20.7%.
e. We are 99% confident that the difference in the population percents of all men and women who are fans of a professional football team is between 13.3% and 20.7%.

Answers

Answer:

e. We are 99% confident that the difference in the population percents of all men and women who are fans of a professional football team is between 13.3% and 20.7%.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

99% confidence interval for the difference  in the proportion of fans of a professional football team between men and women is of (0.133, 0.207)

The interpretation is that we are 99% sure that the true proportion is in this interval for the entire population, so the correct answer is given by option e.

Answers

Answer:

★ Given :

Area of triangle = x² + 8x + 12 cm²

length = (x+6)cm

★ To show :

breadth = (x+2) cm

★ Solution :

We know that,

Area of a rectangle = length × breadth

by putting values

(x² + 8x + 12) = (x+6) × breadth

by diving (x² + 8x + 12) into factors

using middle term splitting

x² + 6x + 2x + 12

x(x+6) + 2(x+6)

= (x+2)(x+6)

(x+2)(x+6) = (x+6) × breadth

Hence, verified..

we know that the equation on the line is given by y equals MX plus b, where M & B are numbers it's is its slope and b is it's y - intercept.

in order to find the equation we must find m and b.

we are going to use two points where the line crosses, in the figure we can see that it crosses points

Suppose C1;C2;C3 are three didifferent biased coins, whose probability of heads equals 0.4, 0.5, and 0.2 respectively. Suppose coins are placed together in a box and you randomly picked a coin from the box. Flip the coin 10 times. Let A denote the event you randomly chose coin C1. Let B denote the event that you got exactly 4 heads out of the 10 coin flips.

Compute the following probabilities:

Solution :

What is the distance between 120 and -130 on a number line?

Answers

Answer:

250

Step-by-step explanation:

120 is 120 spaces from zero

-130 is 130 spaces from zero

130+120=250

250 spaces from each other

Answer:

250

Step-by-step explanation:

You can think of this in different ways. Here are two ways.

1) The distance between any two points on the number line is the absolute value of the difference of the coordinates. Since you will take the absolute value of the difference, it makes no different in which order you do the subtraction.

For points on the number line with coordinates a and b,

distance = |a - b| = |b - a|

Here the coordinates are -130 and 120.

distance = |-130 - 120| = |-250| = 250

distance = |120 - (-130)| = |120 + 130| = |250| = 250

As you can see, the distance comes out the same no matter the order of the subtraction.

distance = 250

2) Just think of what the problem means and do a little calculation.

120 is a positive number, so it is located 120 units to the right of zero.

-130 is a negative number, so it is located 130 units to the left of zero.

To find the distance between the two numbers, think of starting at -130. You need to go 130 units right to reach zero. Then from zero you need to move another 120 units right to reach 120. The total distance is 130 + 120 which equals 250.

distance = 250
