NEED HELP WITH: E, F, G

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 different than 14 minutes. The advocate surveyed 11 randomly selected
people who purchased the Meat Man Barbecue and found that their average time was 12.9 minutes. The standard
deviation for this survey group was 3.3 minutes. What can be concluded at the the a = 0.05 level of significance
level of significance?
a. For this study, we should use

b. The null and alternative hypotheses would be:
Но:

d. The p-value =
e. The p-value is ?

the Meat Man barbecue is equal to 14.
OThe data suggest that the population mean amount of time to assemble the Meat Man barbecue is
not significantly different from 14 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 different
from 14.
OThe data suggest the populaton mean is significantly different from 14 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 different from 14.
