A density curve for all the possible temperatures between 0°F and 20°F is a

rectangle. What is the height of the rectangle in this density curve?

A. 0.5

B. 0.005

C. 0.05

D. 0.0005

The solution is Option C.

The height of the rectangle in this density curve is given by A = 0.05

What is Normal Distribution?

An example of a continuous probability distribution is the normal distribution, in which the majority of data points cluster in the middle of the range while the remaining ones taper off symmetrically toward either extreme. The distribution's mean is another name for the centre of the range.

Normal distributions are symmetric, uni-modal, and asymptotic, and the mean, median, and mode are all equal

A data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean

Given data ,

Let the normal distribution be represented as N

The maximum value of the temperature be a₁ = 20° F

The minimum value of the temperature be a₂ = 0° F

Now , the density curve for all the possible temperatures between 0°F and 20°F is a rectangle

And , the normal distribution function is given by

f ( x ) = 1 / ( b - a ) where

b = a₁  and  a = a₂

Substituting the values in the equation , we get

f ( x ) = 1 / ( 20 - 0 )

On simplifying the equation , we get

f ( x ) = 1/20

f ( x ) = 0.05

Therefore , the value of A is 0.05

Hence , the height of the rectangle is 0.05
