A manufacturer ships toasters in cartons of 50. In each carton, they estimate a 4% chance that one of the toasters will need to be sent back for minor repairs. In a batch of 25,000 toasters, what are the chances that fewer than 950 need to be returned?
The probability that fewer than 950 toasters need to be returned is nothing.
Homework Answers
Ans:
mean=0.04*25000=1000
std. dev=sqrt(25000*0.04*0.96)=30.98
z=(950-1000)/30.98
z=-1.61
P(z<-1.61)=0.0534

A city ballot includes a local initiative that would legalize gambling. The issue is hotly contested, and two groups decide to conduct polls to predict the outcome. The local newspaper finds that 53% of 1600 randomly selected voters plan to vote "yes," while a college Statistics class finds 54% of 350 randomly selected voters in support. Both groups will create 95% confidence intervals. Assume that all voters know how they intend to vote and that the initiative requires a majority...

MIcro-s is a company that manufactures smartphone microprocessors for Phonetelligent, a cellphone manufacturer. Each batch of microprocessor contains 5 microprocessor. The net revenue R obtained by Micro-s for one batch is $50 for each working microprocessor minus $60 for each microprocessor returned by Phonetelligent due to malfunction. Assume that the probability of a microprocessor working properly is 0.80. Let N be the number of returned microprocessors in one batch. What is the probability that 4 or more microprocessors in one...
