There is little difference between the values of t_α_/2 and z_α_/2 when: A)The sample size is small. B)The sample size is large. C)The sample mean is small. D)The sample mean is large. E)The sample standard deviation is small.

Question

Quizplus · Accepted Answer

The values of t_α_/2 and z_α_/2 become nearly equal when the sample size is large (greater than 30). This is because in large samples, the t-distribution approaches the standard normal distribution. Therefore, the difference between the values of t and z becomes negligible.
