Chapter 14: Q. 14.47 (page 570)

In this section, we used the statistic b1as a basis for conducting a hypothesis test to decide whether a regression equation is useful for prediction. Identify two other statistics that can be used as a basis for such a test.

Short Answer

Expert verified

The other two statistics are the coefficient of determination and the correlation coefficient.

Step by step solution

01

Definition

A statistical hypothesis test is a statistical inference method for determining if the data available adequately support a given hypothesis.

02

Explanation

Other statistics that can be utilized as a foundation for such a test include

  • The coefficient of determination r2
  • The correlation coefficientr

Acreage and Value. The document Arizona Residential Property Valuation System, published by the Arizona Department of Revenue, describes how county assessors use computerized systems to value single-family residential properties for property tax purposes. On the WeissStats site are data on lot size (in acres) and assessed value (in thousands of dollars) for a sample of homes in a particular area.

Following are the data on the percentage of investments in energy securities and tax efficiency95%,α=0.05 . find and interpret a confidence interval, at the specified confidence level, for the slope of the population regression line that relates the response variable to the predictor variable.
