**Question:**Based on the line of best fit, which of these statements is true?**Options:**- **A.** It takes about 20 minutes for the equipment to warm up.- **B.** As the number of items in a batch increases by 1, the production time increases by 12 minutes.- **C.** As the number of items in a batch increases by 1, the production time increases by 20 minutes.- **D.** It takes about 60 minutes for the equipment to warm up.*Note: This question requires the analysis of a line of best fit, often found in a scatter plot, to determine the correct statement based on trends in data.* A company produces items in small batches. The machinery needs to warm up before the items can be produced. The scatterplot shows the time needed to produce batches of different numbers of items.**Scatterplot Explanation:**- **X-axis (Horizontal):** Represents the number of items produced, ranging from 0 to 10.- **Y-axis (Vertical):** Represents the production time in minutes, ranging from 0 to 100.**Data Points:**- Each blue dot represents a batch with a specific production time for a given number of items. **Key Points:**- The point (3, 44) indicates that producing 3 items takes 44 minutes.- The point (5, 60) indicates that producing 5 items takes 60 minutes.**Line of Best Fit:**- A red line is drawn through the data points, showing the trend that as the number of items increases, the production time generally increases.This scatterplot helps visualize the relationship between the number of items produced and the production time required.

R3.40. Fuel efficiency Wayne Collier designed an experiment to measure the fuel efficiency of his family car under different tire pressures. For each run, he set the tire pressure to either 28 or 32 psi and then measured the miles driven on a high- way (I-95 between Mills River and Pisgah Forest, NC) until he ran out of fuel using 2-liters of fuel each time. He also used two different types of gasoline (regular and premium). To run the experiment he made some alterations to the normal flow of gasoline to the engine. In Wayne's words, "I inserted a T-junction into the fuel line just before the fuel filter, and a line into the passenger compartment of my car, where it joined with graduated 2 liter Rubbermaid bottle that I mounted in a box where the passenger seat is normally fastened. Then I sealed off the fuel-return line, which under normal operation sends excess fuel from the fuel pump back to the fuel tank." a) Identify the factors and the levels in the experiment. b) How many times…

You put n = 20 rats in a cage that is in a room with a 65-degree temperature. The next day you put them in a cage with a 70-degree temperature. On the final day of the study you put them in a cage with a 75-degree temperature. For each of the three days, you measure how many minutes of each hour they spent running on their exercise wheel. To compare the time they spent running on the wheel between the three different days (in other words, between the three different temperatures of 65, 70, and 75 degrees), what kind of hypothesis test should you do? One-Factor, Independent-Measures ANOVA One-Factor, Repeated-Measures ANOVA Correlation/Regression Chi-Square Goodness of Fit
