**Current Attempt in Progress**Two intervals are given, A and B, for the same value of the explanatory variable.- **A:** 92 to 118- **B:** 84 to 126**(a)** Which interval is the confidence interval for the mean response?[Dropdown Menu]Which interval is the prediction interval for the response?[Dropdown Menu]**(b)** What is the predicted value of the response variable for this value of the explanatory variable?Enter the exact answer.The predicted value is [Text Input Box]---The section appears to be an interactive exercise focusing on distinguishing between confidence intervals and prediction intervals. Users are asked to identify the interval that represents the confidence interval and the one that represents the prediction interval. They are also asked to input the predicted value of the response variable based on the given explanatory variable.

Given Data : A : Range = 26 B : Range = 42 A prediction interval is always wider than the…

The data for this exercise was obtained from https://www.currentresults.com/Weather/Florida/yearly-florida-rainfall.php 2 . Tourists often hear about the wonderful, warm Florida weather; they live in blissful ignorance of the freezes experienced in the northern parts of the state. A tourism organization wants to open up the entire state to tourists. They know that not everyone is drawn to hot, sunny beaches, so they want to advertise the advantages of visiting other parts of the state. One of the first things they need to do is educate potential tourists about the weather. And part of that involves informing them about the average rainfall across the state. Your task is to help the tourism organization figure out what the average rainfall in Florida is like. Rainfall data is provided below. The table below gives the typical yearly rainfall in some parts of Florida. Place Rainfall (inches per year) Monticello 56.8 Niceville 71.0 Tampa 46.3 Lakeland 54.8 St. Augustine Lake City 49.0 52.6…
