Astudy was to be undertaken to determine if a particular training program would improve physical fitness. an
srs of 31 university students was selected to be enrolled in the fitness program. one important measure of
fitness is maximum oxygen uptake. measurements of oxygen uptake in untrained individuals are known to
follow a normal distribution with a mean of ? = 45 ml/kg/min. the researchers wished to determine if there
was evidence that their sample of students differed from the general population of untrained subjects. the
measurements made on the subjects coming into this study produced a mean of x = 47.4 with a standard
deviation of s = 5.3.
what is the approximate p-value for the test?
a) p < 0.005b) 0.005 < p < 0.01c) 0.01 < p < 0.02d) p > 0.02e) p = 0.0118

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
