The state of Virginia has implemented
a Standard of Learning (SOL) test that all public school students
must pass before they can graduate from high school. A passing
grade is 75. Montgomery County High School administrators want to
gauge how well their students might do on the SOL test, but they
don’t want to take the time to test the whole student population.
Instead, they selected 20 students at random and gave them the
test. The results are as follows:
83 79 56
93
48 92 37
45
72 71 92
71
66 83 81
80
58 95 67
78
Assume that SOL test scores are normally distributed.
