Directions: Calculate the mean, median, mode, range, variance, and standard deviation (SD) for each set of data. Please show your work on a separate sheet of paper and submit it along with this worksheet. Make sure your name is on the separate sheet. All answers must be written on this sheet. 1. Data Set: 1, 3, 1, 5, 7, 2, 4, 1, 3, 6, 2, 5, 2, 6, 8, 8, 2, 1, and 3 Mean = _____ Median=_____ Mode=_____ ...
Sample annual salaries (in thousands of dollars) for employees at a company are listed 49 34 58 60 37 37 49 34 58 27 60 49 42 (a) Find the sample mean and sample standard deviation (b) Each employee in the sample is given a $5000 raise. Find the sample mean and sample standard deviation for the revised data set. (c) Each employee in the sample takes a pay cut of $5000 from their original salary. Find the sample mean...
Find the range, variance, and standard deviation for the given sample data, if possible. If the measures of variation can be obtained for these values, do the results make sense? Biologists conducted experiments to determine whether a deficiency of carbon dioxide in the soil affects the phenotypes of poas. Listed below are the phenotype codes, where 1-smooth-yellow, 2 smooth-green, 3-wrinkled yellow, and 4 wrinkled-green. 1 1 4 2 4132 2 2 2 2 2 2 2 3 2 2 2 2 Can the...

The savings account offers 4.0% yearly interest. 5.If an investment opportunity is offered...
4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...
In Exercises 5-20, find the range, variance, and standard deviation for the given sample data. Include appropriate units (such as "minutes") in your results. (The same data were used in Section 3-2 where we found measures of center. Here we find measures of variation.) Then answer the given questions. NCAA Football Coach Salaries Listed below are the annual salaries for a simple random sample of NCAA football coaches (based on data from USA Today). How does the standard deviation change...
