Moment of Methods Estimation
Exercise 6.4-10
6.4-10. Let X1,X2,...,Xn be a
random sample of size n from a geometric distribution for which p
is the probability of success.
(a) Use the method of moments to find a point estimate for
p.
(b) Explain intuitively why your estimate makes good sense.
(c) Use the following data to give a point estimate of p:
3, 34, 7,...
Data
For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5,...
Data
For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1,
7.0, 0.5, 3.9, 2.1, 4.1, 6.5
In Tasks 1-8 you are asked to conduct some computations
regarding this data. The computation should be carried out
manually. All the steps that go into the computation should be
presented and explained. (You may use R in order to verify your
computation, but not as a substitute for conducting the manual
computations.)

For the rest of the lab, you will make
the assumption that your data is approximately normally
distributed. Use Excel to answer the following questions for the
Net Sales data. Copy and paste the output below, don’t
include as a separate file, make sure your x axis is
labelled properly. You will have to “insert” your graphs in the
appropriate places below. Please don’t upload more than one file

Your company has been granted an exclusive license to sell ice
cream. No one has ever sold ice cream here before, so you have no
idea what the demand will look like. You suspect that people like
to buy more ice cream on hotter days, but you are very unsure about
what price you should charge to maximize your profit.

A large buyer of household batteries wants to decide which of
two equally priced brands to purchase. To do this, he takes a
random sample of 100 batteries of each brand. The lifetimes,
measured in hours, of the batteries are recorded in the file
P09_16.xlsx. Before testing for the difference between the mean
lifetimes of these two batteries, he must first determine whether
the underlying population variances are equal.
a. Perform a test for equal population variances. Report a
p-value...
