Find the regression equation, letting the diameter be the predictor (x) variable. Find the best predicted circumference of a marble with a diameter of 1.9 cm. How does the result compare to the actual circumference of 6.0 cm? Use a significance level of 0.05.

The regression equation is y=D+ (Round to five decimal places as needed.)
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
B. The best predicted circumference for a diameter of 1.9 cm is___cm.
C. How does the result compare to the actual circumference?
- Since1.9 cm is within the scope of the sample diameters, the predicted value yields the actual circumference.
- Even though 1.9 cm is within the scope of the sample diameters, the predicted value yields a very different circumference.
- Since1.9 cm is beyond the scope of the sample diameters, the predicted value yields a very different circumference.
- Even though 1.9 cm is beyond the scope of the sample diameters, the predicted value yields the actual circumference.
