Black Bear Grizzly Bear Polar Bear Total
Group 1 24 30 46 100
Group 2 23 34 43 100

I took the quizz and the awnser is 1555

Answer 2

1555 people

Explanation:

First, average the votes for polar bears.

(46 + 43 + 49)/3 = 46

Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.

x/3380 = 46/100

x = 1554.8

Round to the nearest whole number to get 1555.
