Question 1
A) An ACME Bearings manager wants to compare
the average ball bearing
sizes from two different machines. She suspects the mean diameter
for
bearings from machine 2 exceeds that of bearings from machine 1.
She
takes two independent, random samples of size 50, one from
each
machine. The mean and standard deviation of bearings taken
from
machine 1 are 3.302 mm and 0.051 mm. The mean and standard
deviation
of bearings taken from machine 2 are 3.355 mm...

Reactor Systems and Separation Systems
Compare and contrast the different types of reactors used in a
refinery. Summarize your answer in a tabulated form.
Explain the factors affecting the design of reactor
systems.
What are the three major types of economic systems? What are the
effects of economic systems on how organizations are structured in
societies?
can you please put the answer in your own words please and end
please make sure I can read it I have bad eyes
Suppose you sell three types of donuts: plain, nut covered and
chocolate covered. The daily demand of each type of donuts is
normally distributed and independent of each other. The means and
standard deviations are given in the following table:
Mean
Standard deviation
Plain
16
4
Nut covered
20
10
Chocolate covered
25
5
Assume that the
production lead time of making donuts is zero, and you replenish
your inventory of donuts every morning (i.e. review period is one
day)....
