**Problem Description:**A call center data set shows that in a sample of 50 individuals, 19 had prior call center experience. If we assume that the probability that any potential hire will also have experience with a probability of 19/50, what is the probability that among ten potential hires, more than half of them will have experience? Define the parameter(s) for this distribution based on the data.---**Define the Parameters for this Distribution:**Define a success as a new hire having experience. When defining the number of successes, consider what value is necessary if one is going to find the area to the left of that value. Select the correct choice below and fill in the answer box(es) to complete your choice.- **A.** This distribution is a Bernoulli distribution with parameter $ p = \_\_\_ $. (Simplify your answer.) - **B.** This distribution is a binomial distribution with parameters $ n = 10 $ and $ p = 0.38 $. (Simplify your answers.) **[Correct Answer Selected]** - **C.** This distribution is a Poisson distribution with parameter $ \lambda = \_\_\_ $. (Simplify your answer.)---**Final Probability Calculation:**The probability that among ten potential hires, more than half of them will have experience is $\_\_\_$. (Round to three decimal places as needed.)

6. Employers often require their employees to be subjected to random drug testing. Suppose that 5% of employees use a certain type of drug. Drug testing accuracy varies. From years of data collection it is known that those who use this type of drug have ½ 94% chance of testing positive. It is also known that 3% of non-drug users (of the certain type of drug) still test positive. a.) Fill out a probability cross tabulation. b.) If the employee tests positive for a certain drug, what's the probability that the employee uses the drug? c) If the employee tests positive for a certain drug, what's the probability that the employee does NOT use the drug?

Matrimony Monthly is a top-selling magazine that provides information for couples thinking about marriage. Over the years, writers for the magazine have researched just about everything there is to research about weddings. The popular conception at the magazine has been that roughly 50% of first weddings take place indoors in a church, 30% take place indoors in a building other than a church, and 20% take place outdoors This past week, the magazine examined a random sample of 240 first weddings and found the distribution given by the first row of numbers in the table below. (This row contains the frequencies observed in their sample of 240.) The second row of numbers gives the frequencies expected under the hypothesis that the popular conception at the magazine is correct. The bottom row of numbers contains the following value fo each of the wedding location categories. (Observed frequency - Expected frequency ) fE Expected frequency Part 1 Fill in the missing values in the table.…

Does it seem to you that people tend to be absent more on some days of the week than on others? Recently, a major biotechnology firm collected data with the hope of determining whether or not its employees were more likely to be absent on some weekdays than on others. The firm examined a random sample of 110 employee absences. The distribution of these 110 absences is shown in the table below. The observed frequency for each category (each weekday) is shown in the first row of numbers. The second row of numbers contains the frequencies expected for a sample of 110 employees if employee absences at the firm are equally likely on each of the five weekdays. The bottom row of numbers contains the following value for each of the categories. (fo-fE) (Observedrequency Expectedrequency JE Part 1 Fill in the missing values in the table. Round your responses for the expected frequencies to two or more decimal places. 2 Round your responses to three or more decimal places. (SO-SE)² SE Send data…
