Expert Solution & Answer

Explanation of Solution

Statistics:

Statistics is defined as the ‘science of data’, which deals with collection, classification, summarization, organization and analysis of data, interpretation of numerical and categorical data, along with inferring about the nature of the data.

For an example, a researcher wants to find the average height of students of 7^th grade of a certain school. The researcher collects the height of all students of 7^th standard. Now the data should be organized in a well-defined manner or grouped into classes. The researcher uses statistics (mean) to find the average heights of the students, infer about the heights of 7^th grade students in general, and makes a conclusion.

The college hiking club is having a fundraiser to buy new equipment for fall and winter outings. The club is selling Chinese fortune cookies at a price of $2 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of a dinner for two at a local Chinese restaurant. The dinner is valued at $32. Since fortune cookies are donated to the club, we can ignore the cost of the cookies. The club sold 718 cookies before the drawing. Lisa bought 13 cookies. Lisa's expected earnings can be found by multiplying the value of the dinner by the probability that she will win. What are Lisa's expected earnings? Round your answer to the nearest cent.

The Honolulu Advertiser stated that in Honolulu there was an average of 659 burglaries per 400,000 households in a given year. In the Kohola Drive neighborhood there are 321 homes. Let r be the number of homes that will be burglarized in a year. Use the formula for Poisson distribution. What is the value of p, the probability of success, to four decimal places?
