Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 138138 to 194194 cm and weights of 3939 to 150150 kg.
let the predictor variable x be the first variable given.
the 100 paired measurements yield x overbarxequals=167.74167.74 cm, y overbaryequals=81.5681.56 kg, requals=0.3040.304, p-valueequals=0.0020.002, and modifyingabove y with caretyequals=negative 105−105plus+1.161.16x.

find the best predicted value of modifyingabove y with carety (weight) given an adult male who is 158158 cm tall.

use a 0.010.01 significance level.

Use the x-intercept method to find all real solutions of the equation. x^3-10x^2+27x-18=0
