From 1975 to 1986, the general social survey asked its participants if they favored or opposed capital punishment. A least squar

es regression line was calculated to predict the percent that favored the death penalty based on the year. The least squares regression equation is yhat= -1859+0. 9753x. Interpret the slope for this equation.

Based on the information given, it should be noted that the slope cannot be interpreted as the equation makes no sense for the model.

<h3>Interpretation of the slope.</h3>

From the information given, the explanatory variable x was the year that the observations were taken.

In this case, the values are the integer number between 1975 and 1986. The y-intercept of the equation makes no sense for the prediction as it's not in the range of the explanatory data.

<h2>Right answer: I and II only </h2>

If we already have the formula to find how temperature measured in degrees Fahrenheit, relates to a temperature in degres Celsius:

C=(F-32)\frac{5}{9}    (1)

We can know the formula to find how temperature measured in degrees Celsius, relates to a temperature in degres Fahrenheit, only by isolating F:

F=(\frac{9}{5}C)+32    (2)

Having both formulas, let’s begin:

I) If we want to prove that a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 5/9 degree Celsius:

Beginning with 1\ºF:

C=(1\ºF-32)\frac{5}{9}=-17.22\ºC

This means: 1\ºF=-17.22\ºC

Now we are going to increase 1 degree Farenheit. In other words, we are going to use 2\ºF:

C=(2\ºF-32)\frac{5}{9}=-16.66\ºC

This means: 2\ºF=-16.66\ºC

Calculating the difference between -16.66\ºC   and  -17.22\ºC:

-16.66\ºC-(-17.22\ºC)=0,55\ºC>>>>This is equal to 5/9 degree Celsius, hence is correct

II) If we want to prove that a temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit:

Beginning with 1\ºC:

F=(\frac{9}{5}1\ºC)+32  

F=33.8\ºF  

This means: 1\ºC=33.8\ºF  

Now we are going to increase 1 degree Celsius. In other words, we are going to use 2\ºC:

F=(\frac{9}{5}2\ºC)+32  

F=35.67\ºF  

This means: 2\ºC=35.67\ºF  

Calculating the difference between 35.67\ºF   and  33.8\ºF:

35.67\ºF-33.8\ºF=1.8\ºF>>>>This is a proof of the statement, hence is also correct.

<h2 />

III) If we want to prove that a temperature increase of 5/9 degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius:

Beginning with 1\ºC:

F=(\frac{9}{5}1\ºC)+32  

F=33.8\ºF  

This means: 1\ºC=33.8\ºF  

Now we are going to add \frac{5}{9}\ºF:

33.8\ºF+\frac{5}{9}\ºF=34.35\ºF

And use this value in the Celsius formula:

C=(34.35\ºF-32)\frac{5}{9}=1.30\ºC

This means: 1.30\ºC=34.35\ºF

In other words: An increase in 5/9 degree Fahrenheit is equivalent to a temperature increase of 1.30 degree Celsius, <u>not 1 degree Celsius</u>.

Therefore this statement is incorrect.
