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

ivolga24 [154]
We have a point and a slope, so let's use the point slope formula!

(y - y1) = m(x - x1)
where
x1=4
y1=2
and m=3

(y - 2) = 3(x - 4) \\ y - 2 = 3x - 12 \\ y = 3x - 10

What is the slope-intercept form of a linear equation? explain why this form is called the slope-intercept form?
Leviafan [203]
The slope-intercept form of a linear equation is y=mx+b. m being the slope (part one of name) and b being the y-intercept (part 2 of name).
