Can anyone help?:

i have a table i have to work on and i have to create a grid but i never could do it correctly!!

And the questions along was:

use technology to find the equation of the least squares regression line the correlation coefficient and the coefficient of determination round each to three decimal places sketch the line in the scatterplot Interpret The correlation coefficient and the coefficient of determination and then use the equation of the least squares regression line to predict the male life expectancy in Egypt where the female life expectancy is 72 round to one decimal place

i have a pt 2 on this since it cant be long so ill post another afterwards for some help

but please any help is needed because im struggling so bad and nobody can help me!:(

if you can help me i thank you Sooooooo much

I think I can do some

I'm letting x = females and y = males

We have the points

(64, 82) (82, 77) (70, 65) (59, 58) (82, 76) ( 56, 61) (81, 76) (63, 57) ( 74, 70) (80, 76)

Using this website.....https://keisan.casio.com/exec/system/14059929550941

The linear regression equation is

y = .6134x + 26.187

The correlation coefficient = r ≈ .692 [moderate correlation ]

The coefficient of determination = r^2 ≈ .479

Here is the scatterplot :

It appears that we have at least one outlier ....(64, 82)

A cluster appear to be the points (80, 76) (81, 76) ( 82, 76) ( 82, 77)

Hope that helps some.....!!!!
