expected rainfall in 35 days=35*0.05=1.75
and std deviation =0.02*sqrt(35)=0.1183
hence from normal approximation:
probability that the total rainfall in Los Angeles for 35 randomly selected December days =P(X<2)=P(Z<(2-1.75)/0.1183)
=P(Z<2.11)=0.9826

Central limit theorem: Sample mean A worldwide organization of academics claims that the mean IQ score of its members is 115, with a standard deviation of 16. A randomly selected group of 35 members of this organization is tested, and the results reveal that the mean IQ score in this sample is 114.4. If the organization's claim is correct, what is the probability of having a sample mean of 114.4 or less for a random sample of this size? Carry...
