Suppose the people living in a city have a mean score of 54 and a standard deviation of 4 on a measure of concern about the environment Assume that these concem scores are normally distributed Using the 50% - 34% -14% figures, what is the minimum score a person has to have to be in the top (a) 2%, (b) 16%, (C)
50%, (d) 84%, and (e) 98%?
(a) What is the minimum score a person has to have to be in the top 2%?

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
