Two raters, one male and one female, reviewed the same 50 video recordings of police interviews of women suspects and made independent judgments of whether an inappropriate sexist remark was made (+) during the interview or not (-). The ratings are difficult to make and some required judgment calls. The results are as follows: M(+) M(-) E(+) E(-) 5 10 15 5 30 35 10 40 50 A researcher wants to test whether the proportion of “+" judgments is the same for the male and female rater (e.g. HO: PM=PF). The female rater assigned 15, compared to the male's 10, but is this difference consistent with sampling variation? Choose a statistical test, state your reason for the choice, calculate the result, and report your conclusion.
Compound Probability
Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.

Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axioms express probability in terms of a probability space, which assigns a measure with values ranging from 0 to 1 to a set of outcomes known as the sample space. An event is a subset of these outcomes that is described.
Conditional Probability
By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between 0 and 1. The higher the chance of an event occurring, the closer is its value to be 1. If the probability of an event is 1, it means that the event will happen under all considered circumstances. Similarly, if the probability is exactly 0, then no matter the situation, the event will never occur.
