15. fast please.

Exercises 15 -18 refer to the following

The calorie intake content and sodium content (in milligrams) for 8 beef hot dog is compared (source consumer report).

                        x- Calorie Content                  y- Sodium content

                                    181                                          477

                                    176                                          425

                                    149                                          322

                                    184                                          482

                                    158                                          370

                                    139                                          322

                                    175                                          479

                                    148                                          375

  1. The line that best fits the data is 

Group of answer choices

yhat = -205.4429 + 3.7371x

yhat = 3.7371 + 205.4429x

yhat = 205.4429 + 3.7371x

It cannot be defined because there is not enough data

 

 

16.   Is the correlation coefficient significant?

Group of answer choices

no

yes

it might be

Not enough information

 

 

17.   Predict the sodium content for a hot dog that has a calorie content of 135.

Group of answer choices

299 milligrams

710 milligrams

It is not meaningful to predict because the calorie content is not in the proper range.

Not a useful number because the correlation is not significant.

 

  1. If you determine that a point is an outlier, you would

Group of answer choices

ignore it

Use it in the calculation of the sum of squared errors

always delete it and then recalculate the equation of the best fit line

Examine it carefully and try to determine what is causing it to be an outlier.
