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

A sample of 212commercial businesses was surveyed for recycling one commodity; a commodity here means any one type of recyclable material such as plastic or aluminum. Table 11.41shows the business categories in the survey, the sample size of each category, and the number of businesses in each category that recycle one commodity. Based on the study, on average half of the businesses were expected to be recycling one commodity. As a result, the last column shows the expected number of businesses in each category that recycle one commodity. At the 5% significance level, perform a hypothesis test to determine if the observed number of businesses that recycle one commodity follows the uniform distribution of the expected values.
