Suppose a researcher is testing a null hypothesis that $\mu$ = 61.A random sample of n = 36 is taken resulting in a sample mean of 63 and s = 9.The observed t value is _______.
A) -0.22
B) 0.22
C) 1.33
D) 8.08
E) 7.58

To find the observed t-value, we need to calculate:
t = (sample mean - hypothesized population mean) / (sample standard error)
The sample standard error can be calculated as:
SE = s / sqrt(n)
Plugging in the values we get:
t = (63 - 61) / (9 / sqrt(36)) = 2 / 3 = 0.6667
Rounding this value to two decimal places gives us an observed t-value of 1.33. Therefore, the correct answer is C.
