There is a perception that the wastage is depends upon the level of production. You are required to verify this perception, by performing the regression analysis in the last 12-month data given below. After analysis, answers the given question: Write down the value of coefficient of correlation and interpret it. Write down the value of coefficient of determination and interpret it. Write down the regression equation for estimating the wastage in the next month Comments about the validity of regression model (equation) How much will be the estimated wastage if the production level is 5,000,000.

Zagat restaurant guides publish ratings of restaurants for many large cities around the world. The restaurants are rated on a 0 to 30 point scale based on quality of food, decor, service, and cost. Suppose that someone wants to predict the cost of dinner at a restaurant in a city based on the Zagat food quality ratings. If 10 restaurants in a city are sampled and the regression output is given below, what can we conclude about the slope of food quality? Since we are not given the dataset, we do not have enough information to determine if the slope differs from 0. 2) The slope is 2.521 and therefore differs from 0. 3) The slope significantly differs from 0. 4) Not enough evidence was found to conclude the slope differs significantly from 0. 5) The slope is equal to 0.
Find the regression equation, letting overhead width be the predictor (x) variable. Find the best predicted weight of a seal if the overhead width measured from a photograph is 1.7 cm.
