The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.
| Age | 47 | 49 | 51 | 58 | 63 |
|---|---|---|---|---|---|
| Bone Density | 360 | 353 | 336 | 333 | 332 |
Step 2 of 6 :
Find the estimated y-intercept. Round your answer to three decimal places.

| Woman 1 | 47 | 360 | 16920 | 2209 | 129600 |
| Woman 2 | 49 | 353 | 17297 | 2401 | 124609 |
| Woman 3 | 51 | 336 | 17136 | 2601 | 112896 |
| Woman 4 | 58 | 333 | 19314 | 3364 | 110889 |
| Woman 5 | 63 | 332 | 20916 | 3969 | 110224 |
I am able to understand how this problem is solve. Can you break it down for me?

The table below gives the age and bone density for five randomly
selected women. Using this data, consider the equation of the
regression line, yˆ=b0+b1x, for predicting a
woman's bone density based on her age. Keep in mind, the
correlation coefficient may or may not be statistically significant
for the data given. Remember, in practice, it would not be
appropriate to use the regression line to make a prediction if the
correlation coefficient is not statistically significant.
