A researcher is investigating variables that might be associated with the academic performance of high school students. She exam

ined data from 1990 for each of the 50 states plus Washington, DC. The data included information on the following variables.
SATM The average SAT Math score of all high school seniors in the state who
took the exam
$ per pupil The average number of dollars per pupil spent on education by the state
% taking The percentage of high school seniors in the state that took the exam

As part of her investigation, she ran the multiple regression model:
SATM = β0 + β1($ per pupil) + β2(% taking) + εi,
where the deviations εi were assumed to be independent and normally distributed with a mean of 0 and a standard deviation of σ. This model was fit to the data using the method of least squares. The following results were obtained from statistical software.

Source Sum of squares df
Model 45915.0 2
Error 13835.1 48
Variable Coefficient Standard error
Constant 514.652 10.30
$ per pupil 0.00639 0.0025
% taking –1.49221 0.1419

Suppose we wish to test the hypotheses H0: β1 = β2 = 0 versus Ha: at least one of the βj is not 0, using the ANOVA F test.
What is the value of the F statistic?

a) 79.65 b) 24.0 c) 159.3 d) 3.32

70x 6,000 as associative
Vinvika [58]

Answer:

70 x 6000 = 6000 x 70

Explanation:

The associative of multiplication means the items can be regrouped without changing the answer: a(bc) = (ab)c. This means 70 x 6000 = 70 x 6 x 1000.

What is the value of x? <br><br> A. 68° <br> B. 62° <br> C. 112° <br> D. 124
bearhunter [10]
The triangle drawn in the question shows a small single line drawn across two sides of the triangle.

This means that those two sides are equal in length.

Hence, the triangle is an isosceles triangle.

In isosceles triangles, the angles opposite to the equal sides are also equal.

Hence, we know that the two angles other than x is 56°.

The sum of the interior angles of a triangle is 180°

x + 56 + 56 = 180

x = 180 - 56 - 56

x = 180 - 112

x = 68°

Hence, the answer is A.

Answer:

12, 25, 26, 26, 26, 34, 35, 39, 42, 42, 50, 72.

Step-by-step explanation:

A stem and leaf plot works like a digit separator. The left is the first number, which is usually repeated, and the right is the number you add to it.

In this example, 3 is used three times for the numbers 34, 35, and 39.
