E(X) = p V(X) = p(1 p): The Binomial Distribution. Binomial Experiments Consider the following type of random experiment: 1 The experiment consists of n repeated Bernoulli trials - each trial has only two possible outcomes labelled assuccessand failure; 2 The trials areindependent- the outcome of any trial has no e ect on the probability of the others; 3 The probability of success in each... 2 BASIC STATISTICS 1.3.2. Sample variance. The samplevariance is the statisticdeﬁned by S2(X 1,X2,···,Xn)= 1 n− 1 Xn i=1 (Xi − X¯)2 (4) The observed value of S2 in any sampleis demoted by the lower case letter, i.e., s2.

The probability density of the Normal distribution is given by f(x) = 1 ˙ p 2ˇ exp (x )2=2˙2 For the purposes of this course we do not need to use this expression. It is included here for future reference. Calculating probabilities from the Normal distribution For a discrete probability distribution we calculate the probability of being less than some value x, i.e. P(X < x), by simply how to remove the page from pdf 1. Introduction In this unit we explain how to diﬀerentiate the functions lnx and ex from ﬁrst principles. To understand what follows we need to use the result that the exponential constant e is deﬁned
