BNAD 277 EXAM 2024/2025 WITH 100%ACCURATE SOLUTIONS
Question 1:
Pepsi is experimenting with a new machine that fills their cans with
product three times faster than the previous method they were using.
However, they are worried that the increase in speed might be because
the machine is not as accurate. You want to test if the machine is not
filling the cans to the specified 12 ounces. You sample 300 cans filled
by the new machine and find they fill the cans with an average 11.92
ounces with a standard deviation of 0.62 ounces.
Which of the following would be the correct alternative hypothesis for
the above test? - Precise Answer ✔✔The population average from the
new machine is not 12 ounces or μ ≠ 12 ounces

by the new machine and find they fill the cans with an average 11.92
ounces with a standard deviation of 0.62 ounces.
Based on the information from the problem above, which of the
following formulas will you use to calculate the test statistic? Hint: This
will be based on what we know or do not know about the population
,standard deviation. - Precise Answer ✔✔A t test statistic for comparing
means with an unknown population standard deviation.
Question 3:
Pepsi is experimenting with a new machine that fills their cans with
product three times faster than the previous method they were using.
However, they are worried that the increase in speed might be because
the machine is not as accurate. You want to test if the machine is not

by the new machine and find they fill the cans with an average 11.92
ounces with a standard deviation of 0.62 ounces.
Calculate the appropriate test statistic needed to test your claim. Round
your final answer to 4 decimals. Hint: Make sure you are using the
correct formula based on the information given in the problem.This will
be based on what we know or do not know) about the population
standard deviation. - Precise Answer ✔✔- 2.24

Which of the following would be the correct interpretation of the
calculated p-value of 0.013? - Precise Answer ✔✔We are 1.3% unsure
that the population average from the new machine is not 12 ounces.

Using the test statistic, critical value, and/or p-value from the previous
questions, which of the following would be the correct conclusion to
your test using a 5% significance level? Hint: Make sure you know what
is in the alternative hypothesis then use your findings from questions 3-
5. - Precise Answer ✔✔We will reject the null hypothesis, and thus can
conclude that the new machine is not filling the cans to the specified 12
ounces.
Walmart has received numerous customer complaints regarding the
timeliness of their online orders. You are working in operations
management for Walmart and are tasked with checking if these

whether packages are arriving past the 48-hour window. You pull
company data on the 200 most recent deliveries and find an average
delivery time of 48.62 hours and standard deviation of 3.85 hours.
