You believe the population is normally distributed and
you know the standard deviation
is σ=12.3. You obtain a sample mean of M=62.7 for a sample of size n=23.


What is the test statistic for this sample? (Report answer accurate to three decimal places.)

test statistic = correct answer -1.794


What is the p-value for this sample? (Report answer accurate to four decimal places.)

p-value = correct answer 0.0364
