A company performs linear regressions to compare data sets for two similar

tensa zangetsu [6.8K]

Based on the information given, the thing that can be concluded is that Brand A's data are probably linear while Brand B's data are probably not.

<h3>What is a Linear regression?</h3>

It should be noted that a linear regression simply shows the relationship between the dependent and independent variables.

If residuals for brand A are randomly scattered above and below the x-axis, and the residuals for brand B are also randomly scattered but clustered closer to the x-axis, it implies that brand A's data are probably linear while Brand B's data are probably not.

A random scatter of points on the residual plot simply implies that there's a linear relationship in the original data set.

Can someone help me?

mestny [16]

Answer:

Step-by-step explanation:

To do this, we must use the unit circle. At the angle $\frac{\pi }{6}$ the coordinate pair is ( $\frac{\sqrt{3} }{2}$ , $\frac{1}{2}$ ) and the hypotenuse is 1

Now that we know these we can start using the trig functions

sin = y

cos = x

tan = $\frac{y}{x}$

And the other functions would be the reciprocal of these

csc = $\frac{1}{y}$

sec = $\frac{1}{x}$

cot = $\frac{x}{y}$

This would mean that

sinx = $\frac{1}{2}$

cosx = $\frac{\sqrt{3} }{2}$

tanx = $\frac{1}{\sqrt{3} }$ or $\frac{\sqrt{3} }{3}$ if you're supposed to rationalize your denominators

cscx = 2

secx = $\frac{2}{\sqrt{3} }$ or $\frac{2\sqrt{3} }{3}$

cot = $\sqrt{3}$

A random sample of 121 automobiles traveling on an interstate showed an average speed of 65 mph. From past information, it is kn

loris [4]

Answer:

95 percent confidence interval for μ is determined by

(60.688 , 69.312)

a) be the same

Step-by-step explanation:

<u>Step (i)</u>:-

Given data a random sample of 121 automobiles traveling on an interstate showed an average speed of 65 mph.

The sample size is n= 121

The mean of the sample x⁻ = 65mph.

The standard deviation of the population is 22 mph

σ = 22mph

<u>Step (ii) :</u>-

Given The 95 percent confidence interval for μ is determined as

(61.08, 68.92)

we are to reduce the sample size to 100 (other factors remain unchanged) so

given The sample size is n= 100

The mean of the sample x⁻ = 65mph.

The standard deviation of the population is 22 mph

σ = 22mph

<u>Step (iii)</u>:-

95 percent confidence interval for μ is determined by

$(x^{-} - 1.96\frac{S.D}{\sqrt{n} } , x^{-} + 1.96 \frac{S.D}{\sqrt{n} } )$

$(65 - 1.96\frac{22}{\sqrt{100} } , 65 + 1.96 \frac{22}{\sqrt{100} } )$

(65 - 4.312 ,65 +4.312)

(60.688 , 69.312) ≅(61 ,69)

This is similar to (61.08, 68.92) ≅(61 ,69)

<u>Conclusion</u>:-

it become same as (61.08, 68.92)
