Question

Do not perform the tests! For each of the following scenarios answer the following:

A) Write the null and alternative hypothesis.

B) Is it Z or T distribution?

C) Is the test right, left, or two-tailed?

D) What calculator function is used?

E) What decision would you make based on the P-Value that resulted when I did the test? Use a level of significance of 0.05. Why?

F) What would your answer be to the question asked in the scenario?\

**The owner of a professional basketball team claims that
the mean attendance at games is at greater than 18,000, and
therefore the team needs a new arena. A sample of 49 games was
looked at, sample mean and sample standard deviation were
calculated, and a test was done. The P-value is 1.94E-4. Does the
evidence support the owner of the team?**

Answer #1

(A) owner of a professional basketball team claims that the mean attendance at games is at greater than 18,000

So, Null hypothesis

and alternate hypothesis

(B) it is t distribution because the population variance is unknown

(C) It is a right tailed hypothesis because the claim is that the mean is higher than 18000

(D) We will use T TEST under STAT in Ti calculator to calculate the t test statistics

(E) P value given is 1.94E-4, which is less than 0.05 significance level. This result in rejection of null hypothesis.

(F) Yes, there is sufficient evidence to support the claim made by the owner of the professional basketball team because the result is significant at 0.05 level of significance.

When games were sampled from throughout a season, it was
found that the home team won 127 of 198 professional basketball
games and the home team won 57 of 99 professional football games.
At the 5% level of significance, does this indicate that there is a
significant difference between the proportion of home games won by
the two sports?
(1) List all the information necessary for conducting
the hypothesis test and state which
test you are doing.
(2) State the...

For each of the following situations, identify the type of
interval or test you would
perform. Include hypothesis test or confidence interval, mean or
proportion, one sample or two sample
(independent or dependent for two samples). An example of an
answer
would be “hypothesis test, proportion, two samples, independent,
and prop.test(fill in the correct pieces)”
Do not do the test or find the confidence interval.

Paired or not?: In each of the following
scenarios, determine if the data are paired.
(a) We would like to know if there is a "home field" advantage in
professional basketball. To find out, we random select 10 NBA teams
and calculate their average number of points during home games for
the 2019 season. We then calculate their average number of points
during away games for the 2019 season.

SHORT ANSWER. Write the word or phrase that best completes each
statement or answers the question. Assume that a simple random
sample has been selected from a normally distributed population and
test the given claim. Use either the traditional method or P-value
method as indicated. Identify the null and alternative hypotheses,
test statistic, critical value(s) or P-value (or range of P-values)
as appropriate, and state the final conclusion that addresses the
original claim
In tests of a computer component, it...

Determine the critical value(s) of the test statistic for each
of the following small sample tests for the population mean where
the assumption of normality is satisfied. Round your answer to four
decimal places.
Step 1 of 3:
Left-tailed test,α=0.1,n=9
Step 2 of 3:
Right-tailed test ,α=0.05,n=23
Two-tailed test, α=0.1,n=27 (negative and positive critical
values)

Perform the following tests answering each part. Assume random
samples taken from populations that are normally distributed. The
health of employees is monitored by weighing them. A sample of 54
employees has a mean weight of 185 lb and σ is known to be 26.2 lb,
use a 0.10 sig. level to test the claim that the population mean of
employees weights is less than 200 lb.

A medical laboratory claims that the mean turn-around time for
performance of a battery of tests on blood samples is 1.98 business
days. The manager of a large medical practice believes that the
actual mean is larger. A random sample of 45 blood samples yielded
mean 2.05 and sample standard deviation 0.13 day. Perform the
relevant test at the 10% level of significance, using these
data.
