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.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.

12 dolars one is cheaper becasue 3 pairs is 6 means is sock is 2 while the 12 is cheaper
