Twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006). On a particular weekend, 35 automobile
Bingel [31]

Answer:

Step-by-step explanation:

Given that twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006).

considering the total number of vehicles, probability for a randomly drawn vehicle not covered by insurance = 0.23

Each vehicle can be treated as independent of the other

Hence X no of vehicles not covered by insurance is Binom with n = 35 and p - 0.23

a) the expected number of these automobiles that are not covered by insurance=E(x) =

np = 35(0.23)\\= 8.05

b) the variance

=npq = 8.05(0.77) \\=6.1985

Std dev = square root of variance = 2.4897
