State the decision and conclusion (in a complete sentence) for the following preconceived levels of \(\alpha\).

\(\alpha=0.01\)

a. Decision:____

b. Reason for the decision:____

c. Conclusion:(write out in complete sentence):___

Short Answer

Expert verified

Part a. Decision: here \(\alpha=0.01\) so “reject the null hypothesis”.

Part b. Reason for the decision: \(p-value<\alpha\) so \(p-\)value is \(0\).

Part c. Conclusion (write out in a complete sentence): reject the null hypothesis so the alternative got accepted so there is sufficient evidence to conclude that smoking level is dependent on the ethnic group.

Step by step solution

01

Part a. Step 1. Explanation

\(\alpha=0.01\)

Decision: here \(\alpha=0.01\) so “reject the null hypothesis”.

02

Part b. Step 1. Explanation

\(\alpha=0.01\)

Reason for the decision: \(p-value<\alpha\) so \(p-\)value is \(0\).

03

Part c. Step 1. Explanation

\(\alpha=0.01\)

Conclusion (write out in a complete sentence): reject the null hypothesis so the alternative got accepted so there is sufficient evidence to conclude that smoking level is dependent on the ethnic group.

The average waiting time in a doctor’s office varies. The standard deviation of waiting times in a doctor’s office is 3.4 minutes. A random sample of 30 patients in the doctor’s office has a standard deviation of waiting times of 4.1 minutes. One doctor believes the variance of waiting times is greater than originally thought.

What type of test should be used?

Use a solution sheet to solve the hypothesis test problem. Go to Appendix E for the chi-square solution sheet. Round expected frequency to two decimal places.

A manager of a sports club keeps information concerning the main sport in which members participate and their ages. To test whether there is a relationship between the age of a member and his or her choice of sport, 643members of the sports club are randomly selected. Conduct a test of independence.

What is the p-value?

Suppose an airline claims that its flights are consistently on time with an average delay of at most 15minutes. It claims that the average delay is so consistent that the variance is no more than 150minutes. Doubting the consistency part of the claim, a disgruntled traveler calculates the delays for his next 25flights. The average delay for those 25flights is 22minutes with a standard deviation of 15minutes.

If an additional test were done on the claim of the average delay, but 45 flights were surveyed, which distribution would you use?

chi-square test statistic = ________
