Find the regression​ equation, letting the first variable be the predictor​ (x) variable. Using the listed​ lemon/crash data, wh
kakasveta [241]

The regression analysis evaluates the amount of relationship that exists

between the variables in the analysis.

  • The regression equation is; \underline{\overline y = -0.00255 \cdot \overline x + 16.47268}
  • The prediction is worthwhile because it gives an idea of the observed Crash Fatality Rate and it is therefore approximately correct.

Reasons:

First part;

The given data is presented as follows;

\begin{tabular}{|cc|c|}Lemon Imports (x) &&Crash Fatality Rate\\232&&16\\268&&15.7\\361&&15.4\\472&&15.5\\535&&15\end{array}\right]

The least squares regression equation is; \overline y =  b \cdot \overline x + c

Where;

b = \mathbf{\dfrac{\sum \left(x_i - \bar x\right) \times \left(y_i - \bar y\right) }{\sum \left(x_i - \bar x\right )^2 }}

\overline y = The mean crash fatality = 15.52

\overline x = The mean lemon import = 373.6

Therefore;

b = \dfrac{-171.36 }{67093.2 } = -0.00255

c = \overline y - b·\overline x = 15.52 - (-0.00255)×373.6 = 16.47268

Therefore;

  • The regression equation is \underline{\overline y = -0.00255 \cdot \overline x + 16.47268}

Second part;

When the imports is 425 metric tons of lemon, we have;

\overline y = -0.00255 × 425 + 16.47268 = 15.38893 ≈ 15.4

Therefore;

When the import is 425 metric tons, the Crash Fatality Rate ≈ 15.4

Given that the predicted value is between the values for 268 and 535, we

have that the prediction is approximately correct or worthwhile

<u>The prediction is worthwhile</u>

ICE Princess25 [194]

Answer:

<em>120°, 120°, 60°, 60°</em>

Step-by-step explanation:

m∠1 = 180° - 60° = 120°

m∠1 = m ∠2 (alternate interior)

m∠3 = 60° (vertical to given angle)

m∠4 = m∠3 (alternate exterior)
