Given: null hypothesis is that the population mean is 16.9 against the alternative hypothesis that the population mean is not equal to 16.9. A random sample of 16 items results in a sample mean of 17.1 and the sample standard deviation is 2.4. It can be assumed that the population is normally distributed. Determine the observed "t" value.
A) t = 2.12
B) t = 1.33
C) t = 1.753
D) t = 0.33

The observed t-value is calculated using the formula: t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size)). Substituting the given values: t = (17.1 - 16.9) / (2.4 / sqrt(16)) = 0.33.
