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<3.5|x<4)?

Short Answer

Expert verified

The value of theP(x<3.5x<4)is0.80.

Step by step solution

01

Given information

Table,

Sample mean = 2.50

Standard deviation = 0.8302

02

Solution

The probability density function to calculate P(x<3.5x<4)for 1.5x4.5will be:

f(x)=141.5

=12.5

Thus, the value of P(x<3.5x<4)is:

P(x<3.5x<4)=(3.51.5)×12.5

=2×12.5

=0.80
