The commercial for the new Meat Man Barbecue claims that it takes 19 minutes for assembly. A consumer advocate thinks that the assembly time is different than 19 minutes. The advocate surveyed 12 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 16.7 minutes. The standard deviation for this survey group was 2.9 minutes. What can be concluded at the the a = 0.05 level of significance level of significance? a. For this study, we should use |Select an answer b. The null and alternative hypotheses would be: Ho: ? Select an answer H1: ? Select an answer c. The test statistic ? v (please show your answer to 3 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 |Select an answer v | the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the population mean amount of time to assemble the Meat Man barbecue is not significantly different from 19 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 19. The data suggest the populaton mean is significantly different from 19 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 19. The data suggest the population mean is not significantly different from 19 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 19
