Researchers collected data from 100 randomly chosen counties in Texas on pollution levels and asthma rates. Pollution levels wer

e measured by calculating the average number of air particulates (in mg/m3) and asthma rates were calculated as the percent of residents (0-100%) diagnosed with asthma. After confirming all relevant assumptions, they ran a linear model predicting asthma rates based on pollution level: Estimate Std. Error (Intercept) 3.61 2.05 pollution 0.78 0.29 Are pollution levels in Texas counties a significant linear predictor of asthma rates

Answer:

The answer is "3.14".

Step-by-step explanation:

The coefficient of pollution level is "b" and "a" intercept

\to y=a+bx\\\\  

We must verify it.

H_0 :\beta = 0\\\\H_a : \beta \neq 0\\\\

Beta \to b=1.76, SE=0.56 \ Estimate

The statistics on tets are now provided

\to t=\frac{b}{SE}=\frac{1.76}{0.56}=3.14

Because statistics will be more than critical (1.984) values, we thus rejectH_0

A bag has 8 bagels. three of the bagels are cranberry. what percent of the bagels are cranberry
Olin [163]
Since 3 out of 8 are cranberry, the fraction is 3/8. In order to convert it, you divide the top number by the bottom, and you get 0.375. In order to get the percent, you would multiply it by 100, and you get 37.5 %

The answer is 37.5%

Factor Completely: 12x2 − 44x + 24 A) 2(2x − 6)(3x − 2) B) 4(x − 3)(3x − 2) C) 6(x − 4)(2x − 1) D) 12(x − 1)(x − 2)
Elan Coil [88]

Answer:

B) 4(x - 3)(3x - 2)

Step-by-step explanation:

12x² - 44x + 24

4[3x² - 11x + 6]

4[3x² - 9x - 2x + 6]

4[3x(x - 3) - 2(x - 3)]

4(x - 3)(3x - 2)

Using the number line as a guide, work out the difference between the numbers given.
inn [45]

Answer:

If these are addition:

1) 7

2) 3

3) 1

4) -3

5) 0

6) -5

If they are subtraction:

1) 9

2) 9

3) -7

4) 7

5) -4

6) 3

Step-by-step explanation:

Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.

This is how the problems would be set up:

Addition:

1) 8+(-1)= 7

2)6+(-3)= 3

3)-3+4= 1

4)2+(-5)= -3

4)-2+(-2)= 0

6)-1+(-4)= -5

Subtraction:

1) 8-(-1)= 9

2)6-(-3)= 9

3)-3-4=- 7

4)2-(-5)= 7

4)-2-(-2)= -4

6)-1-(-4)= 3
