Question

The commercial for the new Meat Man Barbecue
claims that it takes 9 minutes for assembly. A
consumer advocate thinks that the assembly time is
higher than 9 minutes. The advocate surveyed 14
randomly selected people who purchased the Meat
Man Barbecue and found that their average time was
9.7 minutes. The standard deviation for this survey
group was 2.2 minutes. What can be concluded at
the the a = 0.05 level of significance level of
significance?
a. For this study, we should use
z-test for a population proportion v
b. The null and alternative hypotheses would be:
Ho:
H1:
c. The test statistic (t
1.191
(please
show your answer to 3 decimal places.)
d. The p-value = 0.1169
(Please show your
answer to 4 decimal places.)
e. The p-value is
? ▼
a
f. Based on this, we should | Select an answer
the null hypothesis.
g. Thus, the final conclusion is that ...
The data suggest that the population
mean amount of time to assemble the
Meat Man barbecue is not significantly
higher than 9 at a = 0.05, so there is
statistically insignificant evidence to
conclude that the population mean
amount of time to assemble the Meat
Man barbecue is higher than 9.
The data suggest the population mean
is not significantly higher than 9 at a =
0.05, so there is statistically
insignificant evidence to conclude that
the population mean amount of time to
assemble the Meat Man barbecue is
equal to 9.
The data suggest the populaton mean is
significantly higher than 9 at a =
0.05,
so there is statistically significant
evidence to conclude that the
population mean amount of time to
assemble the Meat Man barbecue is
higher than 9.
