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

\(\alpha=0.05\)

a. Decision:____

b. Reason for the decision:____

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

Short Answer

Expert verified

Part a. Decision: here \(\alpha=0.05\) so “reject the null hypothesis”.

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

Part c. Reject the null hypothesis so the alternative got accepted so there is sufficient evidence to conclude that smoking level is dependent on ethnic group.

Step by step solution

01

Part a. Step 1. Explanation

\(\alpha=0.05\)

Decision: here \(\alpha=0.05\) so “reject the null hypothesis”.

02

Part b. Step 1. Explanation

\(\alpha=0.05\)

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

03

Part c. Step 1. Explanation

\(\alpha=0.05\)

Reject the null hypothesis so the alternative got accepted so there is sufficient evidence to conclude that smoking level is dependent on ethnic group.

Is there a difference between the distribution of community college statistics students and the distribution of university statistics students in what technology they use on their homework? Of some randomly selected community college students, 43 used a computer, 102 used a calculator with built in statistics functions, and 65 used a table from the textbook. Of some randomly selected university students, 28 used a computer, 33 used a calculator with built in statistics functions, and 40 used a table from the textbook.

Table11.43

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?
