# Answer to Question #2786 in Statistics and Probability for Alex

Question #2786

Solve this poblem:

Use the normal distribution to calculate the probability that a randomly selected new home in your state has an advertised selling price above $300,000. For estimates of μ and σ, use X-BAR and s. See your posting to the activity in Week 2's conference for the values of X-BAR and s.

Z=X-mean/standard deviation

z= 300,000-279,477.88/196,525.174

Specific requirements:

Please put the answer in the example format below:

Z=X-mean/standard deviation

z=300,000-698,411.50/950074.54

z= -0.419=.3372

1-.3372=0.6628

=66.28%

Expert's answer

Z=X-mean/standard deviation

z= 300,000-279,477.88/196,525.174

z = .1044

p = .5416

1 - .5416=0.4584

=45.84%
