1. The theorem that states that the sampling distribution of the sample mean is approximately normal when the sample size n is reasonably large is known as the:

A. central tendency theorem
B. point estimate theorem
C. simple random sample theorem
D. central limit theorem

 

2. In a normal distribution, changing the standard deviation:

A. splits the distribution to two curves
B. makes the curve more or less spread out
C. shifts the curve left or right
D. makes the curve more robust

Additional Information

These multiple choice questions based on the Statistics. The first question is about sample size and sample mean being normal for a large sample and the second question is about standard deviation in normal distribution.
