a) What is the probability that fewer than 5 of the 20 sampled invoices receive the discount? bi What is the probability that more than 5 of the 20 sampled invoices receive the discount? z. A mechatronic assembly is subjected to a final functional test. Suppose that defects occur at random in these assemblies, and that defects occur according to a Poisson distribution with parameter λ=4 what is the probability that an assembly will have 2 or fewer defects? Bi Calculate the mean - Calculate the standard deviation. 4. The output voltage of a power supply is normally distributed with mean 5 V and standard deviation 2.4 V. If the lower and upper specifications for voltage are 4.95 V and 5.05 V, respectively, what is the probability that a power supply selected at random will conform to the specification on voltage?
4. Determine the sample median t. Determine the sample mode D. Determine the lower and upper quartiles. Determine the Interquartile Range i Determine the range i. State the data required for the construction of a box plot for these data. 2. A large industrial firm allows a discount on any invoice that is paid within 30 days. Of all invoices, 22% receive the discount. In a company audit, 20 invoices are sampled at random. (HINT: Binomial Distribution, Excel Function: BJNOSDJST(x,n,p, camalative)) a) What is the probability that feucr iban 5 of the 20 sampled invoices receive the discount? b) What is the probability that more than 5 of the 20 sampled invoices receive the discount?
