please help me i am so lost in all this

The number of cell phones per 100 residents in countries in Europe is given in table #1 for the year 2010.The number of cell phones per 100 residents in countries of the Americas is given in table #2 also for the year 2010 ("Population reference bureau," 2013).

What is the confidence interval estimate of the difference₁- ₂:

Enter lower bound value to nearest ten-thousandth, followed by < , followed by"1-2" for difference, followed by <, followed by upper bound value to nearest ten-thousandth.No spaces between any characters. Do not use italics, but if mathematically necessary use negative signs.Examples:

0.0077<1-2<0.0780

13.1012<1-2<18.3941

-9.7300<1-2<-3.0008

Using the confidence interval, select the most correct description of the result of the survey:

A.We estimate with 98% confidence that the sample mean number of cell phones per 100 residents in countries of Europe is anywhere from 4.3641 to 37.5276 more than the mean number of cell phones per 100 residents in countries of the Americas.

B.We estimate with 98% confidence that the true mean number of cell phones per 100 residents in countries of Europe is anywhere from 4.3641 to 37.5276 more than the mean number of cell phones per 100 residents in countries of the Americas.

C.We estimate with 98% confidence that the true proportion of cell phones per 100 residents in countries of Europe is anywhere from 4.3641 to 37.5276 more than the mean number of cell phones per 100 residents in countries of the Americas.

D.We estimate with 98% confidence that the mean number of cell phones per 100 residents in countries of Europe is anywhere from 4.3641 to 37.5276 less than the mean number of cell phones per 100 residents in countries of the Americas.
