# Question: Suppose you are planning to buy a car that weighs

Suppose you are planning to buy a car that weighs 3500 pounds, and you have a linear model that predicts gas mileage (y) given the weight of the car (4. Which do you think would be more appropriate, a confidence interval for the mean gas mileage of cars that weigh 3500 pounds, or a prediction interval for the mileage of a particular car that weighs 3500 pounds? Explain.

Compute the least-squares regression line for predicting power (y) from wind speed (x). Soil quality: Soil scientists conducted an experiment in which the mineral gypsum was added in four different amounts to soil specimens to try to control the acid level of the soil. Three soil specimens received each amount ...Using the data in Exercise I, can you conclude that the pH differs with the amount of gypsum added? Use the a = 0.05 level of significance. One-way analysis of variance requires the assumption that the populations are approximately normal. However, if the sample sizes are large (n > 30), this assumption is not so important. Why is this so? Following are the prices, in dollars, of a sample of 20 air conditioners. Can you conclude that the median price differs from $300? Use a = 0.01 level of significance.Post your question
