Question

Duke Energy reported that the cost of electricity for an efficient home in a particular neighborhood of Cincinnati, Ohio, was $108 per month (Home Energy Report, Duke Energy, March, 2012). A researcher believes that the cost of electricity for a comparable neighborhood in Chicago, Illinois, is higher. A sample of homes in this Chicago neighborhood will be taken and the sample mean monthly cost of electricity will be used to test the following null and alternative hypotheses. H 0: μ ≤ $108 H a: μ > $108

a. Assume the sample data lead to rejection of the null hypothesis. What would be your conclusion about the cost of electricity in the Chicago neighborhood?

b. What is the Type I error in this situation?

The Type I error is - Select your answer -accepting rejecting
Item 2 *H* _{0} when it is - Select your answer
-true false Item 3 .

c. What are the consequences of making this error?

A type I error is Select rejecting accepting Item 4 the null hypothesis and assuming Chicago Select has higher has lower or equal does not have higher Item 5 electricity costs than Cincinnati, when in fact it Select has higher has lower or equal does not have lower or equal Item 6 electricity costs than Cincinnati.

d. What is the Type II error in this situation?

The Type II error is - Select your answer -accepting rejecting
Item 7 *H* _{0} when it is - Select your answer
-true false Item 8 .

e.What are the consequences of making this error?

A type II error is Select rejecting accepting Item 9 the null hypothesis and assuming Chicago Select has higher does not have higher does not have lower or equal Item 10 electricity costs than Cincinnati, when in fact it Select has higher has lower or equal does not have higherItem 11 electricity costs than Cincinnati.

**Pls, comment if any issue.**

Duke Energy reported that the cost of electricity for an
efficient home in a particular neighborhood of Cincinnati, Ohio,
was $103 per month (Home Energy Report, Duke Energy, March, 2012).
A researcher believes that the cost of electricity for a comparable
neighborhood in Chicago, Illinois, is higher. A sample of homes in
this Chicago neighborhood will be taken and the sample mean monthly
cost of electricity will be used to test the following null and
alternative hypotheses.

SCG&E reported that the cost of electricity for an efficient
home in Charleston, SC was $125 per month. A researcher believes
that the cost of electricity for a comparable neighborhood in
Charlotte, NC is lower A sample of homes in Charlotte is taken to
test the following hypotheses.
H0: µ ≥ $125
Ha: µ < $125
Assume that the sample data resulted in the rejection of the
null hypothesis. What would be your conclusion about the cost of
electricity in...

Suppose U.S. consumers 21 years and older consumed 26.4 gallons
of beer and cider per person during 2017. A distributor in
Milwaukee believes that beer and cider consumption are higher in
that city. A sample of consumers 21 years and older in Milwaukee
will be taken, and the sample mean 2017 beer and cider consumption
will be used to test the following null and alternative
hypotheses:
H0: μ ≤ 26.4
Ha: μ > 26.4
(a) Assume the sample data led...

Earlier, we considered data from the GSS on numbers of close
friends people reported having. The mean for this variable is 7.44,
with a standard deviation of 10.98. Let's say that you decide to
use the GSS data to test whether people who live in rural areas
have a different mean number of friends than does the overall GSS
sample. Again, treat the overall GSS sample as the entire
population of interest. Let's say you select 40 people living in...

#14 Three years ago, the mean price of an existing
single-family home was $243 comma 700. A real estate broker
believes that existing home prices in her neighborhood are higher.

what it would mean to make a Type I error. (c) Explain what it
would mean to make a Type II error. (a) State the hypotheses.

You are looking for a way to incentivize the sales reps that you
are in charge of. You design an incentive plan as a way to help
increase in their sales. To evaluate this innovative plan, you take
a random sample of your reps, and their weekly incomes before and
after the plan were recorded. You calculate the difference in
income as (after incentive plan - before incentive plan). You
perform a paired samples t-test with the following hypotheses: Null...

Question 11 (1 point)
A comparison between a major sporting goods chain and a
specialty runners' store was done to find who had lower prices on
running shoes. A sample of 34 different shoes was priced (in
dollars) at both stores. To test whether the average difference is
less than zero, the hypotheses are as follows: Null Hypothesis:
μD ≥ 0, Alternative Hypothesis: μD < 0. If
the average difference between the two stores (specialty -...

It is believed that 11% of all Americans are left-handed. A
college needs to know how many left-handed desks to place in the
big lecture halls being constructed on its campus. In a random
sample of 200 students from that college, 30 were left-handed. Does
this provide enough evidence to show that students at this college
have a higher percentage of left-handers than the general American
population? Set up the hypotheses.
a.) Fill in the correct null and alternative hypotheses:...
