Suppose a government department would like to investigate the relationship between the cost of heating a home during the month of February in the Northeast and the home's square footage. The accompanying data set shows a random sample of 10 homes. Construct a 90% prediction interval to estimate the cost in February to heat a Northeast home that is 3,100 square feet.

Heating Cost($) Square_Footage
340 2430
300 2430
300 2020
260 2220
310 2310
460 2630
330 2210
400 3140
330 2530
380 2910

An electronics retailer would like to investigate the relationship between the selling price of a digital camera and the demand for it. The table shown below gives the weekly demand for the camera in one particular market along with the corresponding price. These data have a sample correlation coefficient, rounded to three decimal places, of -0.930. Using a significance level of 0.10, test if the population correlation coefficient between the selling price and the demand for the camera is less...
