1. Out of 300 guests this is how the guest answered on a survey:
2. Answered "Poor" to room quality. 142 out of 300
3. Answered "Poor" to food quality. 147 out of 300
4. Answered "Poor" to service quality. 154 out of 300
5. Develop the 98% confidence interval for the proportion of all recent clients that were "dissatisfied."
6. Develop the 98% confidence interval for the proportion of all recent clients who answered "Poor" to room quality.
7. Conduct a hypothesis test (using either the p-Value Approach or the Critical Value Approach) to determine if the proportion of all recent clients is more dissatisfied than the traditional level of dissatisfaction. Use α = 0.08. Do not forget to include the correctly worded hypotheses and show all the steps required to conduct the hypothesis test.
