### Confidence Interval Calculation for Grocery Spending SurveyIn a survey of 151 households, a Food Marketing Institute found that 53 households spend more than $125 a week on groceries. To find the 90% confidence interval for the true proportion of households that spend more than $125 a week on groceries, you need to select the appropriate calculator from the options below:1. Confidence Interval for a Population Proportion2. Confidence Interval for a Population Mean Given Statistics3. Hypothesis Test for a Population Mean Given Statistics4. Two Independent Sample Means Comparison Given Data5. Chi-Square Test for Goodness of Fit6. Chi-Square Test for Independence7. Two Independent Sample Means Comparison Given Statistics8. One-Way ANOVA9. **Confidence Interval for a Population Mean Given Data** (incorrect selection)10. Hypothesis Test for a Population Proportion11. Two Dependent Sample Means Comparison Given Data12. Hypothesis Test for a Population Mean Given Data13. Two Independent Proportions ComparisonThe correct selection should be **Confidence Interval for a Population Proportion**. This choice is essential because the data involves determining a proportion of households fitting a certain spending category.### Tasks:a. **Enter your answer as an open-interval** using decimals (not percents) accurate to three decimal places: - Confidence interval = (____, ____)b. **Express the same answer as a tri-linear inequality** using decimals (not percents) accurate to three decimal places: - ____ < p < ____c. **Express the same answer using the point estimate and margin of error**. Provide your answers as decimals, to three places: - p = ____ ± ____This framework guides users through calculating and interpreting the confidence interval accurately.

b) The margin of error for the proportion of all adults who think things are on the wrong track for 90% confidence is 0.039. Would the margin of error be larger or smaller for 95% confidence? Explain. Choose the correct answer below. A. To be more confident, the interval needs to contain the true proportion more often, so the margin of error would be smaller. B. To be more confident, the interval needs to contain the true proportion more often, so the margin of error would be larger. O C. To be more confident, the interval needs to contain the true proportion less often, so the margin of error would be smaller. D. To be more confident, the interval needs to contain the true proportion less often, so the margin of error would be larger.

He randomly selects 12 students whose teachers reprimand in private and 12 students whose teachers reprimand in public. At the end of the year he determines the number of misbehaviors for each student. For the public condition and mean=7.7 and s=4.1 for the private condition mean=4.2 and s=3.5. Which method is more effective? What is the percentage of variance accounted for by the method of reprimand? What is the power of your test?
