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.

Questions which rely on knowledge of standard integrals.

6 questions on standard statistical distributions.

Binomial, Poisson, Normal, Uniform, Exponential.

3 questions. One question on limits of standard sequences. Other two on finding least $N$ such that $|a_n-L |\lt 10^{-r},\;\;n \geq N$ where $L$ is limit of $(a_n)$.
