1)From a population of 200 elements, the standardard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is_________.

The choices were: a)3, b)2(I picked this one because I thought - the standard deviation of the standard error was = 14/sqrt of the sample size 49), c)greater than 2, and d)less than 2.

2)We want to draw a simple random sample of 50 elements from a population of 500 elements. On the first selection, the probability of an element being selected is______

The choices were: a)0.100, b)0.010 c)0.001 and d)0.002. I picked a).

I missed a good deal more than these two, but I thought I had these correct.

Thanks,
