The commercial for the new Meat Man Barbecue claims that it takes 14 minutes for assembly. A
consumer advocate thinks that the assembly time is higher than 14 minutes. The advocate surveyed
13 randomly selected people who purchased the Meat Man Barbecue and found that their average
time was 14.7 minutes. The standard deviation for this survey group was 3.8 minutes. What can be
concluded at the the a = 0.10 level of significance level of significance?
a. For this study, we should use t-test for a population mean
b. The null and alternative hypotheses would be:
Ho:
Select an answer v
"H: ? v| Select an answer v
c. The test statistic ?
|(please show your answer to 4 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is >v a
f. Based on this, we should fail to reject
]* the null hypothesis.
g. Thus, the final conclusion is that.
O The data suggest the population mean is not significantly higher than 14 at a = 0.10, so
there is not enough evidence to conclude that the population mean amount of time to
assemble the Meat Man barbecue is equal to 14.
O The data suggest the populaton mean is significantly higher than 14 at a = 0.10, so there
is enough evidence to conclude that the population mean amount of time to assemble
the Meat Man barbecue is higher than 14.
The data suggest that the population mean amount of time to assemble the Meat Man
barbecue is not significantly higher than 14 at a = 0.10, so there is not enough evidence
to conclude that the population mean amount of time to assemble the Meat Man
barbecue is higher than 14.
