For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: [7 \\ Select an answer (please enter a decimal) Hy: [? V Select an answer (Please enter a decimal) C. The test statistic z = (please show your answer to 3 decimal places.) d. The critical value - ? (Please show your answer to 3 decimal places.) e. The test statistic Select an answer V in the rejection region. f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population proportion is not significantly smaller 59% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 59%. The data suggest the population proportion is not significantly smaller 5% at a = 0.05, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 59%. The data suggest the populaton proportion is significantly smaller 59% at a = 0.05, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is smaller 59% Hint: Help Helpful Videos: Calculations .

A consumer advocate thinks that the assembly time is higher than 12 minutes. The advocate surveyed 14 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 13.6 minutes. The standard deviation for this survey group was 2.3 minutes. What can be concluded at the the o - 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 \\ Select an answer HI: 7 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 Vill 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 12 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 higher than 12. The data suggest the population mean is not significantly higher than 12 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 12. The data suggest the populaton mean is significantly higher than 12 at or = 0.05, so there is statistically significant evidence to conclude that the population mean amount of time to
