A scientific study on speed limits gives the following data table.
| Average speed limit | Average annual fatalities |
|---|---|
| 25 | 16 |
| 27 | 29 |
| 29 | 38 |
| 32 | 71 |
| 35 | 93 |
Using technology, it was determined that the total sum of squares (SST) was 4029.2, the sum of squares regression (SSR) was 3968.4, and the sum of squares due to error (SSE) was 60.835. Calculate R2 and determine its meaning. Round your answer to four decimal places.
Select the correct answer below:
R2=0.0153
Therefore, 1.53% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=0.9849
Therefore, 98.49% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=0.0151
Therefore, 1.51% of the variation in the observed y-values can be explained by the estimated regression equation.
R2=1.0153
Therefore, 10.153% of the variation in the observed y-values can be explained by the estimated regression equation.

Table 2.5 (page 109) gives data on the true calories in 10 foods
and the average guesses made by a large group of people. Exercise
2.26 explored the influence of two outlying observations on the
correlation.
(a) Make a scatterplot suitable for predicting guessed calories
from true calories. Circle the points for spaghetti and snack cake
on your plot. These points lie outside the linear pattern of the
other 8 points.
(b) Find the least-squares regression line of guessed calories...

We wish to see if, on average, traffic is moving at the posted
speed limit of 65 miles per hour along a certain stretch of
Interstate 70. On each of four randomly selected days, a randomly
selected car is timed and the speed of the car is recorded. The
observed sample mean speed is 70 mph and the sample standard
deviation is 4.08 mph. Assume that speeds are normally distributed
with mean μ. Which of the following is the 95%...

The table below gives data from a study that shows that social
exclusion causes "real pain." That is, activity in the area of the
brain that responds to physical pain goes up as distress from
social exclusion goes up. The scatterplot for this data shows a
moderately strong linear relationship. The data are given
