The owner of a farmer's market was interested in determining how many oranges a person buys when they buyoranges. He asked the cashiers over a weekend to count how many oranges a person bought when they boughtoranges and record this numberanalysis at a later time. The data is given below in the table. The random variable xrepresents the number of oranges purchased and P(x) represents the probability that a customer will buy x oranges.Determine the variance of the number of oranges purchased by a customer.

34% of likely U.S. voters think that the federal government should get more involved in fighting local crime. You randomly select six likely U.S. voters and ask them whether they think that the federal government should get more involved in fighting local crime. The random variable represents the number of likely U.S. voters who think that the federal government should get more involved in fighting local crime. Find the variance of the binomial distribution. σ2=nothing (Round to the nearest tenth as needed.)
Anyone who has been outdoors on a summer evening has probably heard crickets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This phenomenon was studied in detail by George W. Pierce, a physics professor at Harvard.
