Question

The commercial for the new Meat Man Barbecue claims that it takes 13 minutes for assembly. A consumer advocate thinks that the assembly time is higher than 13 minutes. The advocate surveyed 14 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 14.4 minutes. The standard deviation for this survey group was 3.4 minutes. What can be concluded at the the αα = 0.10 level of significance level of significance?

For this study, we should use
The null and alternative hypotheses would be:

H0:H0:

H1:H1:

The test statistic = (please show your answer to 3 decimal places.)
The p-value = (Please show your answer to 4 decimal places.)
The p-value is αα
Based on this, we should the null hypothesis.
Thus, the final conclusion is that ...
- The data suggest the population mean is not significantly higher than 13 at αα = 0.10, so there is statistically insignificant evidence to conclude that the population mean amount of time to assemble the Meat Man barbecue is equal to 13.
- The data suggest that the population mean amount of time to assemble the Meat Man barbecue is not significantly higher than 13 at αα = 0.10, so there is statistically insignificant evidence to conclude that the population mean amount of time to assemble the Meat Man barbecue is higher than 13.
- The data suggest the populaton mean is significantly higher than 13 at αα = 0.10, so there is statistically significant evidence to conclude that the population mean amount of time to assemble the Meat Man barbecue is higher than 13.
