These questions are designed to give students on questions to do with statistics. They are basic but gives a small understanding on mean, variance and standard deviation. There are also some definitions.

Provided with information on a sample with sample mean and standard deviation, but no information on the population variance, use the t test to either accept or reject a given null hypothesis.

Seven standard elementary limits of sequences. 

Two ordered data sets, each with 10 numbers. Find the sample standard deviation for each and for their sum.

Sample of size $24$ is given in a table. Find sample mean, sample standard deviation, sample median and the interquartile range.
