TABLE 13-11 A Computer Software Developer Would Like to Use the Number

question 67

True/False

TABLE 13-11
A computer software developer would like to use the number of downloads (in thousands)for the trial version of his new shareware to predict the amount of revenue (in thousands of dollars)he can make on the full version of the new shareware.Following is the output from a simple linear regression along with the residual plot and normal probability plot obtained from a data set of 30 different sharewares that he has developed:
-True or False: Referring to Table 13-11,there is sufficient evidence that revenue and the number of downloads are linearly related at a 5% level of significance.

Definitions:

Three-Phase Circuit

An electrical circuit design that uses three alternating currents, each of which reaches its peak value at one third of a cycle from the other, to efficiently supply power.

Phase Values

Phase values pertain to the specific measurements or quantities that characterize each phase in a multiphase electrical system, such as voltage or current levels.

Pure Reactive Load

An electrical load that consumes reactive power only, with a power factor of zero, meaning it does not dissipate real power.

Three-Phase Load

An electrical load operating with three phases of alternating current, providing more consistent, balanced power delivery.
