A hospital director is told that 21% of the treated patients are uninsured. The director wants to test the claim that the percentage of uninsured patients is above the expected percentage. A sample of 200 patients found that 50 were uninsured. At the 0.05 level, is there enough evidence to support the director's claim? *State the null and alternative hypotheses. *Find the value of the test statistic. Round your answer to two decimal places. *Specify if the test is one-tailed or two-tailed. *Determine the P-value of the test statistic. Round your answer to four decimal places. *Identify the value of the level of significance. *Make the decision to reject or fail to reject the null hypothesis. *State the conclusion of the hypothesis test.
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.
