Question 11 (1 point)
A suggestion is made that the proportion of people who have food
allergies and/or sensitivities is 0.48. You believe that the
proportion is actually less than 0.48. The hypotheses for this test
are Null Hypothesis: p ≥ 0.48, Alternative Hypothesis: p < 0.48.
If you select a random sample of 28 people and 12 have a food
allergy and/or sensitivity, what is your test statistic and
pvalue?

Question 12 (1 point)
Suppose the national average dollar amount for an automobile
insurance claim is $911.9. You work for an agency in Michigan and
you are interested in whether or not the state average is less than
the national average. The hypotheses for this scenario are as
follows: Null Hypothesis: μ ≥ 911.9, Alternative Hypothesis: μ <
911.9. You take a random sample of claims and calculate a pvalue
of 0.3314 based on the data, what is the appropriate conclusion?
Conclude at the 5% level of significance.
Question 12 options:

1)

We did not find enough evidence to say the true average claim
amount is less than $911.9. 


2)

We did not find enough evidence to say the true average claim
amount is higher than $911.9. 


3)

We did not find enough evidence to say a significant difference
exists between the true average claim amount and $911.9. 


4)

The true average claim amount is significantly less than
$911.9. 


5)

The true average claim amount is higher than or equal to
$911.9. 

Question 13 (1 point)
Do sit down restaurant franchises and fast food franchises
differ significantly in stock price? Specifically, is the average
stock price for sitdown restaurants greater than the average stock
price for fast food restaurants? If sit down restaurants are
considered group 1 and fast food restaurants are group 2, what are
the hypotheses of this scenario?
Question 13 options:

1)

H_{O}: μ_{1} ≥ μ_{2}
H_{A}: μ_{1} < μ_{2} 


2)

H_{O}: μ_{1} > μ_{2}
H_{A}: μ_{1} ≤ μ_{2} 


3)

H_{O}: μ_{1} = μ_{2}
H_{A}: μ_{1} ≠ μ_{2} 


4)

H_{O}: μ_{1} ≤ μ_{2}
H_{A}: μ_{1} > μ_{2} 


5)

H_{O}: μ_{1} < μ_{2}
H_{A}: μ_{1} ≥ μ_{2} 

Question 14 (1 point)
In a consumer research study, several Meijer and Walmart stores
were surveyed at random and the average basket price was recorded
for each. You wish to determine if the average basket price for
Meijer is different from the average basket price for Walmart. It
was found that the average basket price for 24 randomly chosen
Meijer stores (group 1) was $62.528 with a standard deviation of
$11.453. Similarly, a random sample of 18 Walmart stores (group 2)
had an average basket price of $60.241 with a standard deviation of
$11.4754. Perform a two independent samples ttest on the
hypotheses Null Hypothesis: μ_{1} = μ_{2},
Alternative Hypothesis: μ_{1} ≠ μ_{2}. What is the
test statistic and pvalue of this test? You can assume that the
standard deviations of the two populations are statistically
similar.
