z Chapter 4 Quiz pt 1 of9 (6 complete)Y A frequency disiribution is showm below Complete parts (a) and (b) The number of televisions per household in a small town Households 24448720 1404 (a) Use the frequency distibution to construct a probability distribution. P(x) (Round to three decimal piaces as needed) (b) Graph the probability distribution using a histogram. Choose the correat graph of the distribution below O A. Describe the histogram's shape. Choose the correct answer below O symmetre O skewed right O skewed loh ek to select your enswers.

Explanation / Answer

Solution :

Given that Televisions 0 , 1 , 2 , 3
Households 24 , 448 , 729 , 1404

(a) Let x represent the number of televisions for a randomly selected household. Construct a probability distribution for the above data.

P(x) = x/n , For x = 0,1,2,3 and n = 24+448+729+1404 = 2605

P(0) = 24/2605 = 0.009

P(1) = 448/2605 = 0.172

P(2) = 729/2605 = 0.280

P(3) = 1404/2605 = 0.539
  

x P(x)
-------------
0 0.009
1 0.172
2 0.280
3 0.539
