Suppose that the average trip time from Oak Park to UIC on the Blue line is 22 minutes and that the standard deviation of the population is 16 minutes (sigma=16). We are interested to know whether the average trip time on Thursdays is longer. We study a sample of 49 trips on Thursdays and the average is 23.75 minutes. Execute a hypothesis test at alpha=5% that the average trip time on Thursdays is longer (that is, that it requires a larger number of minutes). State Ho, Ha, calculate the appropriate statistic, p-value, state whether you reject Ho vs. not and state your conclusion in plain English.

What is the smallest number of minutes that will allow you to reject Ho?

What is the probability that you will reject Ho if mu is actually 22.875 minutes?

Fill in the probabilities in the table below. Also indicate alpha, beta and power.
What test concludes Ho is true in population Ho not true in population Reject Ho
Not reject Ho

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known at 0.5 minutes. We want to test to determine whether or not the mean waiting time of all customers is significantly different than 3 minutes. Use α = 0.05. 14. The test statistic is a. 1.96 b. 1.64 c. 2.00 d. 0.056...

Exercise 10-6 (LO10-4) The waiting time for customers at MacBurger Restaurants follows a normal distribution with a population standard deviation of 1 minute. At the Warren Road MacBurger, the quality-assurance department sampled 50 customers and found that the mean waiting time was 2.75 minutes. At the 0.05 significance level, can we conclude that the mean waiting time is less than 3 minutes? State the null hypothesis and the alternate hypothesis. State whether the decision rule is true or false: Reject...

Suppose a candidate running for sheriff in a rural community claims that he will reduce the average speed of emergency response to less than 30 minutes (30 minutes is thought to be the average response time, µ = 30 with the current sheriff). Thanks to his campaign promise, he is elected sheriff and keeps careful records of response times. Since the sheriff was elected, there have been 9 emergency calls (N = 9) with a mean response time of 15...

The American Bar Association reports that the mean length of time for a hearing in juvenile court is 25 minutes. Assume that this is your population mean. As a lawyer who practices in the juvenile court, you think that the average hearing is much shorter than this. You take a random sample of 20 other lawyers who do juvenile work and ask them how long their last case in juvenile court was. The mean hearing length for this sample of...

Question 1 (1 point) Saved It is reported in USA Today that the average flight cost nationwide is $327.31. You have never paid close to that amount and you want to perform a hypothesis test that the true average is actually different from $327.31. What are the appropriate hypotheses for this test? Question 1 options: 1) HO: μ ≤ 327.31 HA: μ > 327.31 2) HO: μ ≥ 327.31 HA: μ < 327.31 3) HO: μ ≠ 327.31 HA: μ...

On average, a banana will last 7 days from the time it is purchased in the store to the time it is too rotten to eat. Is the mean time to spoil less if the banana is hung from the ceiling? The data show results of an experiment with 16 bananas that are hung from the ceiling. Assume that that distribution of the population is normal. 7.5, 7.6, 5, 6.5, 4.4, 8.2, 7, 4.4, 4.5, 5.3, 5.7, 6.4, 6.4, 7.8,...

Question 1 (1 point) Suppose the national average dollar amount for an automobile insurance claim is $746.9. You work for an agency in Michigan and you are interested in whether or not the state average is different from the national average. Treating the national mean as the historical value, What are the appropriate hypotheses for this test? Question 1 options: 1) HO: μ ≤ 746.9 HA: μ > 746.9 2) HO: μ > 746.9 HA: μ ≤ 746.9 3) HO:...

A current survey of 38 lawyers found an average salary of $120,000, with a sample standard deviation of $10,000. We don’t know the true population mean or variance for lawyers’ salaries. Suppose that US news publishes an article saying the average lawyer’s salary in the US is $125,000, and you want to test for whether the true average salary is different than that amount What is the null and alternative hypothesis for the above test? (1 POINT) What are the...
