Question 1086794: 3. Which is greater? Explain.
a) The z-value that cuts off the top 1% of a distribution -OR- the t-value that cuts off the top 1% of a distribution?

b) The standard deviation of a sample -OR- the standard error of the mean?

The z-value is always less than the t-value for any given per cent. (infinitely, they are the same).
sd of the sample is always greater than or equal to the SE of the mean.
sd of sample is s
SE of mean is s/ sqrt(n); unless n is 1, SE is less than s.
