The data that follow are the square footage (in 1,000 feet squared) of 28 homes.

The sample mean = 2.50 and the sample standard deviation = 0.8302. The distribution can be written as X~U(1.5,4.5).

What is P(x=1.5)?

Short Answer

Expert verified

The value of theP(x=1.5)is zero.

Step by step solution

01

Given information

Table,

Sample mean = 2.50

Standard deviation = 0.8302

02

Solution

Because the probability of a single point is always zero because the region under the curve for any given single point is always 0, the value of P(x=1.5) will be 0.
