Question

Suppose IQ scores were obtained for 2020 randomly selected sets of couplescouples. The 2020 pairs of measurements yield x overbarxequals=103.62103.62?, y overbaryequals=103.25103.25?, requals=0.9050.905?, ?P-valueequals=?0.000, and ModifyingAbove y with caret equals 0.53 plus 0.99 xy=0.53+0.99x?, where x represents the IQ score of the wifewife. Find the best predicted value of ModifyingAbove y with carety given that the wifewife has an IQ of 9595?? Use a significance level of 0.05.

Q: The best predicted value of ModifyingAbove y with carety is?

Explanation / Answer

here as p value for correlation test is significant ; therefore we can conclude that there is a valid linear regression

hence best predicted value Y =0.53+0.99*95 =94.58
