Save your answers to a Word or Excel document. 5.8 Recall from Example 5.5 that Sound City also sells the ClearTone-400 satelite car radio. For this radio, historical sales records over the last 100 weeks show 6 weeks with no radios sold, 30 weeks with one radio sold, 30 weeks with two radios sold, 20 weeks with three radios sold, 10 weeks with four radios sold, and 4 weeks with five radios sold. Estimate and write out the probability distribution of x, the number of ClearTone-400 radios sold at Sound City during a week. Your answer should have six results to include P(x) for x 0, 1,2, 3, 4 and 5 radios (1 pt

Explanation / Answer

The porbability distribution is as follows :

P[X=x] = 6/100 =0.06 when x= 0 ;

= 30/100=0.30 when x=1 ;

=30/100=0.30 when x=2

= 20/100 = 0.20 when x =3

= 10/100 = 0.10 when x = 4

= 4/100 = 0.04 when x= 5

ie, P[X=x] = 0.06 , when x=0

= 0.3 when x=1

= 0.3 when x = 2

= 0.2 when x=3

= 0.1 when x=4

= 0.04 when x=5
