a). What are p-type
semiconductors? What are their differences comparing with n-type
semiconductors?
b).
Moore’s law predicts the rapid and steady growth in the number of
transistors contained on a single microcircuit chip. Why do
engineers want to increase the number of transistors contained on a
single microcircuit chip?

1. A company wishes to estimate the profit from two
new products. The estimated cost of producing the first product is
€3 per unit and it is expected to sell for €5 per unit while the
second product costs €5 per unit and is expected to sell for €8 per
unit. The first product takes 1 hour of packaging time per day
while the second one takes 2 hours of packaging time per day. The
time taken for delivery of...
A customer wants to estimate the average delivery time of a
pizza from the local pizza parlor. Over the course of a few months,
the customer orders 28 pizzas and records the delivery times. The
average delivery time is 20.06 with a standard deviation of 5.271.
If the customer estimates the time using a 95% confidence interval,
what is the margin of error?

From 25 samples, each with size 10, you estimated that the
hospital’s EHR downtime average time was 30 minutes with the
standard deviation of 2 minutes. Your process is assumed stable and
normally distributed.
(a) What is the potential capability of the system to meet the
specifications of ??? = 10 minutes and ? ?? = 45 minutes?
(b) What is the actual capability of the system to meet the
specifications of ??? = 10 minutes and ? ?? =...
