Customers arrive to a bank teller according to a Poisson process with a mean rate of 10/hr. Forty percent of the customers need to make a bank deposit only. Fifty percent need to make a withdrawal. The rest of the customers need special assistance from a bank consultant. The bank is open to the public between 9:00 AM and 5:00 PM.

c. What is the expected number of bank-consultant-seekers customers that will arrive during the 8-hr workday?
d. What is the probability of exactly 10 customers arriving between 12:00 PM and 1:00 PM?
e. What is the probability exactly of four deposit-only customers arriving, four withdrawal-only customers, and two bank-consultant-seeker customers between 12:00 PM and 1:00 PM?

The weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to ac voltage. the values of the parameters depend on the voltage and temperature; suppose α = 2.5 and β = 190. (a) what is the probability that a specimen's lifetime is at most 250? less than 250? more than 300? (round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) what is the probability that a specimen's lifetime is between 100 and 250? (round your answer to four decimal places.) (c) what value is such that exactly 50% of all specimens have lifetimes exceeding that value? (round your answer to three decimal places.) hr
