Using software with the given data, find and interpret the
multiple correlation and Upper R squared for the relationship
between yequalscollege GPA, x 1equalshigh school GPA, and x
2equalsstudy time. Use both interpretations of Upper R squared as
the reduction in prediction error and the percentage of the
variability explained.

Find the probability and interpret the results. If convenient,
use technology to find the probability. The population mean annual
salary for environmental compliance specialists is about $61,000. A
random sample of 43 specialists is drawn from this population. What
is the probability that the mean salary of the sample is less than
$ 59,000? Assume σ= $6,100.
The probability that the mean salary of the sample is less than
$59,000 is ____ (Round to four decimal places as
needed.)
