For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10. The 50 paired ratings yield x overbarxequals=6.36.3, y overbaryequals=6.16.1, requals=negative 0.200−0.200, P-valueequals=0.1630.163, and ModifyingAbove y with caretyequals=7.577.57negative 0.232−0.232x. Find the best predicted value of ModifyingAbove y with carety (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is xequals=88. Use a 0.050.05 significance level.

^Y/X=8= 5.714

Step-by-step explanation:

Hello!

Given the variables

Y: Attractiveness ratings by females of their male partners

X: Attractiveness ratings by males of their female date partners

Each member of the couple rated the attractiveness of the other in a scale from 1 to 10

A sample of 50 randomly selected speed dates were taken and the linear regression model estimated

^Y= 7.57 - 0.232X

You have to find the best-predicted value of Y for a date in which the attractiveness rating by the male of the female is X=8

To find this value you have to replace the value of X is the estimated equation:

^Y= 7.57 - 0.232X= 7.57 - 0.232*8= 5.714

I hope this helps!

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
