## Understanding Confidence and Prediction Intervals**Problem Statement:**Two intervals are given, A and B, for the same value of the explanatory variable.- **A:** 2.2 to 7.0- **B:** 2.1 to 7.1### Questions:**(a) Which interval is the confidence interval for the mean response?**- **Dropdown Choice for Selection****Which interval is the prediction interval for the response?**- **Dropdown Choice for Selection****(b) What is the predicted value of the response variable for this value of the explanatory variable?**- Enter the exact answer.- **Input Box for Predicted Value****Resources Available:**- eTextbook and Media- Hint Option**Note:** There are three attempts allowed for this question. You can save your progress to continue later.--- ### Explanation:- **Confidence Interval:** This is used to estimate the uncertainty around the mean response of a population. It’s typically narrower. - **Prediction Interval:** This provides a range for predicting an individual response, and it’s usually wider than the confidence interval.Understanding these concepts can aid in determining which interval relates to the mean response and which pertains to the individual predictions.

The intervals are 2.2 to 7.0 and 2.1 to 7.1.

A confidence interval for a mean is (-11, 10). This interval would be wider if The sample mean was larger or the variability of the data was larger. The investigator wanted to be more confident of their results, or there was more information. The variability of the data was small, or the sample mean was larger. The variability of the data was larger, or the investigator wanted to be more confident. None of the above.

The x? test statistic for a goodness of fit follows where f, is the observed frequency for category i, e, is the expected frequency for category i, and k is the number of categories. The appropriate x? has k - 1 degrees of freedom. x² = (f, - e)? %3D i = 1 The observed and expected frequencies are summarized in the table below. Expected Frequency Squared Difference Squared Difference Divided by Expected Observed Difference Category Frequency fj - ej (f - e,)? Frequency e 3,600 A (-60)? : 20 80 20 - 80 = -60 = 3,600 80 B 80 80 100 40 3,600 90 The sum of the final column will be the x test statistic. Thus, the test statistic is x? = There are k = 3 categories, so the degrees of freedom is k - 1 Enter an exact number.
