Answer #1

Describe how you could use a confidence interval to analyze a
portion a dataset in a way that would help the owner of the
restaurant better understand his customers. Be sure to use proper
statistical terminology. You do not have to actually calculate the
confidence interval

Describe in detail how you would construct a 95% confidence
interval for a set of 30 data points whose mean is 20 and
population standard deviation is 3. Be sure to show that you know
the formula and how to plug into it.
Also, clearly state the margin of error.

A)
How could you ensure that medical terminology resources or
checklists/documentation you have produced are accurate and
relevent to the requirements of your practise?
B) what would you do if you weren't sure?
C) what do you need to do to ensure that all staff members use
ans interpret accurate medical terminology specific to a
pracise?

Identify the statistical and mathematical tools you can use to
determine the predictors for the level of leisure-time physical
activity (make sure that your data contains at least four
variables).
A. Provide reasons for using these tests.
B. Determine the most appropriate test(s) to use to analyze the
data.
C. Describe how you would utilize the selected statistical
test(s) to understand and interpret the data.

Confidence intervals seek to estimate a population parameter
with an interval of values calculated from an observed sample
statistic. Demonstrate that you understand this concept by
describing a situation in which one could use a sample mean or
sample proportion to produce a confidence interval as an estimate
of a population mean or population proportion. I am asking you to
make up a situation where a confidence interval might be computed.
Clearly identify the population, sample, parameter, and statistic
involved...

Unwanted calls (including illegal and spoofed robocalls) are the
FCC's top consumer complaint. The United States is the
8th most spammed country in the world, and the annoying
calls are on the rise according to a new report. Suppose that a
spammer is testing a scheme to get people to buy something over the
phone and getting the “customer” to provide...

CONFIDENCE INTERVAL PROJECT – Day 3
On this sheet, you will be calculating 95% Confidence
Intervals for your data. Fill in all of the values for each piece,
the formula, then show the full calculation for the CI. Write the
CI in 2 different ways:
In + notation
In interval notation: ( ________ , ________
)
When you record standard deviation- round to the nearest
tenth.
Use the back of this sheet if extra space is
needed.

Part 1: Product Strategy
Briefly describe a product or service that you use and enjoy.
Where is it in the product development life cycle? What
recommendations do you have for improving the offering to fit your
needs better? Be sure to consider the following:
What level of quality and consistency does the offering
have?
How many features does it have and can they be removed or
added?
Does the design and/or service deliver what the customer
values? If not, how...

QUESTION 3
Which of the following increases the range of a confidence
interval (select all that apply)?
Decreasing the confidence level
Decreasing the standard deviation
Increasing the sample size
Increasing the standard deviation
Decreasing the same size
Increasing the confidence level
12 points
QUESTION 4
As I've mentioned, sample size is so important because it's the
only way we learn about the population. But in one of the
techniques we've discussed, sample size is particularly important.
Which one is...

I am trying to figure out how to find the test statistic using
Excel. I understand the formula- that I need to use parameter 'p'
and 'normal distribution' ….z= sample proportion and minus the
'population portion' then we divide p*q and divide n -sample size.
I understand how to populate the data in the formula. I just can't
figure out how to solve this using Excel. (my only option with my
class) I need step by step directions if possible....
