I need to know the answer to a probability question.

The total number of employees is 30,000

Annually 25% of the total employees will be selected randomly for a drug test.

Annually 10% of the total employees will be selected randomly for a alcohol test.

Annual drug & alcohol random selections will be spread out equally over the course of 4 quarters. Annual selections for drug and alcohol will be done independently of one another.

What is the probability of being selected for both drug and alcohol tests in the same quarter?

How many employees could be selected for both drug and alcohol on any given quarter in the course of a year?

looking over 8 years of data what would be the annual avreage of this type of selection?

Are you good with statistics? Part A: Exploratory Data

Part A: Exploratory Data Analysis Preparation Open the files for the course project and the data set. For each of the five variables, process, organize, present and summarize the data. Analyze each variable by itself using graphical and numerical techniques of summarization. Use Excel as much as possible, explaining what the results reveal. Some of the following graphs may be helpful: stem-leaf diagram, frequency/relative frequency table, histogram, boxplot, dotplot, pie chart, bar graph. Caution: not all of these are appropriate for each of these variables, nor are they all necessary. More is not necessarily better. In addition be sure to find the appropriate measures of central tendency, the measures of dispersion, and the shapes of the distributions (for the quantitative variables) for the above data. Where appropriate, use the five number summary (the Min, Q1, Median, Q3, Max). Once again, use Excel as appropriate, and explain what the results mean. Analyze the connections or relationships between the variables. There are ten possible pairings of two variables. Use graphical as well as numerical summary measures. Explain the results of the analysis. Be sure to consider all 10 pairings. Some variables show clear relationships, while others do not. … read more
