In a sample of 40, the mean is x¯x¯ = 94.90 with a standard deviation of s = 9.46. Assuming the results follow a normal distribution, construct the 90% confidence interval for the population mean. Multiple Choice 90% confidence interval is 92.68 ± 1.685. 90% confidence interval is 97.42. 90% confidence interval is between 92.38 and 97.42. 90% confidence interval is 94.90 ± 2.22.
A recent publication states that the average closing cost for purchasing a new home is $8431. A real estate agent believes the average closing cost is more than $8431. She selects 10 new home purchases and finds that the average closing costs are $8458 with a standard deviation of $250. Help her decide if she is correct by testing her claim at a=0.01. The correct hypotheses would be: Ο Η: μ $8431 (claim) Ο Η : μ > $8431 HA:µ < $8431 (claim) Ο H: μ $8431 HA: µ + $8431 (claim) Since the level of significance is 0.01 the critical value is 2.821 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that the average closing cost is more than $8431. There is not enough evidence to reject the claim that the average closing cost is more than $8431. O There is enough evidence to support the claim that the average closing cost is more…

The average American consumes 84 liters of alcohol per year. Does the average college student consume less alcohol per year? A researcher surveyed 14 randomly selected college students and found that they averaged 74.4 liters of alcohol consumed per year with a standard deviation of 21 liters. What can be concluded at the the αα = 0.01 level of significance? H0: H1: The test statistic: The p-value = he p-value is ? a Based on this, we should Select an answer accept fail to reject reject the null hypothesis. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly less than 84 at αα = 0.01, so there is statistically significant evidence to conclude that the population mean amount of alcohol consumed by college students is less than 84 liters per year. The data suggest that the population mean amount of alcohol consumed by college students is not significantly less than 84 liters per year at αα = 0.01, so there is statistically insignificant…
