Complete parts (a) through (d) below a. What are the mean and standard deviation of the number of online retail orders that turn out to be fraudulent? The mean number of online rtal onders tht tum out to be taudulent is Type an ineger or a decimal Round to four deoimal places as needed) Enter your answer in the answer box and then click Check Answer remaining Clear AllExplanation / Answer
n= 25 and p= 0.06
mean= np= 25*0.06= 1.5
q= 1-p= 1-0.06= 0.94
variance= npq= 25*0.06*0.94= 1.41
std= sqrt(variance)= sqrt(1.41)= 1.1874
