Question 1192030: sample size is 28.
sample mean is 17.5
sample standard deviation is 4.3 hours.
since you are using sample standard deviation rather than population standard deviation, the use of the t-score is indicated.
degrees of freedom is sample size minus 1 = 27.
critical t-score at .05 significance level

1.703 is the critical value for t if a one-way test.
2.052 the value if a 2-way test.
t=(x bar-17.5)/4.3/sqrt(28)
