A group of 8 students is chosen at random. Find the probability that a exactly 5 have access to the internet. The grades of a group of students in an exam are normally distributed with a mean of 70 and a standard deviation of A student from this group is selected randomly.
In a certain country last year a total of million tons of trash was recycled.
The chart below shows the distribution, in millions of tons, for the different types of trashes.Statistics is a branch of applied mathematics concerned with collecting, organizing, and interpreting data. The data are represented by means of graphs. Statistics is also the mathematical study of the likelihood and probability of events occurring based on known quantitative data or a collection of data.

Below are some hints and ideas to try so that you can do well in your statistics and mathematics courses. This course provides an elementary introduction to probability and statistics with applications.
Topics include: basic combinatorics, random variables, probability distributions, Bayesian inference, hypothesis testing, confidence intervals, and linear regression. The Spring version of this subject employed the residential MITx system, which enables on-campus subjects to provide MIT.
In the first two years it is usually straightforward to move between the Mathematics course and the Mathematics and Statistics course, subject to the availability of space on the course and to the consent of your college. What is Mathematics & Statistics? Mathematics is the abstract science of numbers, quantity and space.
Mathematics may be studied in its own right (pure mathematics), or as it is applied to other disciplines such as physics and engineering (applied mathematics).
