Answer:
84.13%
Step-by-step explanation:
Given data:
mean μ= 100 and standard deviation= 35
P(x>65)=
putting vales we get
P(z>(65-100)/35)=P(z>-1) or P(z<1).,
from normal distribution table we get
P(z<1)= 0.8413= 84.13%
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) =
b) the variance
=
Std dev = square root of variance = 2.4897
