What can be concluded at the the or = 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: 7 v Select an answer V H1: 7v Select an answer c. The test statistic ? ~ = (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 ? 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 18 at o = 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 18. The data suggest the populaton mean is significantly higher than 18 at o - 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 18. The data suggest the population mean is not significantly higher than 18 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 18.
