Question
1. You are applying for a job at two companies. Company A offers starting salaries with $27,000 and $3,000, Company B offers starting salaries with }= $27,000 and = $7,000. From which company are you more likely to get an offer of $33,000 or more? Choose the correct answer below A. Company B, because data values that lie within one standard deviation from the mean are considered very usual B. No difference, because data values that lie more than three standard deviations from the mean are considered very unusual Company A, because data values that lie more than two standard deviations from the mean are considered C. 2. Use the box-and-whisker plot to determine if the shape of the distribution represented is symmetric, skewed left, skewed right, or none of these Choose the correct answer below none of these skewed left symmetric skewed right 40 8020 160 200 3.

Data set (i), because it has no entries near the mean C.Explanation / Answer
1)
Company B, because data values that lie within one standard deviation from the mean are considered very usual.
because company B has a greter SD so the data can variate more than A
Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 7, maximum = 60, 6 classes
7, 16, 25, 34, 43, 52
se a Pareto chart to display the data. The data represent the numbers of times medicationdispensing errors were detected during a 2month study.
Choose the correct Pareto chart.
What are the most common types of medicationdispensing errors?
Data set (iii), because its data have more variability.
Which data set has the least sample standard deviation?
Data set (ii), because it has more entries that are close to the mean.
How are the data sets the same? How do they differ?
The three data sets have the same standard deviations but have different ranges.
