Using traditional methods it takes 12.012.0 hours to
receive a basic flying license. A new license training method using
Computer Aided Instruction (CAI) has been proposed. A researcher
used the technique on 2222 students and observed that
they had a mean of 11.811.8 hours with a variance
of 1.961.96. Is there evidence at
the 0.0250.025 level that the technique reduces the
training time? Assume the population distribution is approximately
normal.

Find the value of the test statistic. Round your answer to three
decimal places.
