"Affordable" Diamond Pricing Imagine you have set out to purchase a diamond, and you want all the
information you can possibly get before the purchase. You run an Internet
search on diamonds to learn more about the different cuts, carat ranges, color
values, and so on. After having researched a bit, you've decided on the basic
cut, quality, color, and weight range that you can probably afford.
This diamond pricing spreadsheet e gives three snapshots of a large set of
data on diamond pricing. The 0.30-0.40 Carats tab gives the 2012 data on
diamonds ranging from 0.30 to 0.40 carats.
Part A
Go to the Subset tab, which gives a subset of randomly chosen data from the
first tab. Go to your Math Tools and open the Graph tool. Plot the data of
weight (carat) versus price in this tab using the +Data button (Note that you
can copy two columns of data and use "paste table data"). Export an image of
the plot, and paste it in the space below. Find the equation of the regression
line (using a Best Fit Linear relationship) and the value of the correlation
coefficient (0)

step-by-step explanation:

i found the life tables for the year 2012. 

life table of males at age 30. probability of dying between ages x and x+1

total population:  

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:  

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

i think the answer is c sorry if it's wrong
