Part 1: Preliminary Discussion and Data Collection Suppose that you have been hired by a glove manufacturing company to provide information for their manufacturing process. In this part of your study, we will focus on pinkie finger length of adults. 1. Discuss possible reasons for providing a Statistical Report on pinkie lengths. 2. Provide one decision the client might make based on the results of your study. 3. List two factors that might influence pinkie length of a person. Part 2: Collect, record and analyze your data 1. We have collected data from a sample of 1000 people. The sample has mean 1 and standard deviation 0.1. 2. The data is measures from the "V" in between the fourth and fifth fingers to the tip of the pinkie finger.1 TOFEET 2 23 34 Part 3: Descriptive Statistics 1. Open a new R Script in RStudio 2 . Record the sample mean and sample standard deviation as "sample_mean" and "sample_sd". 3. Define upper and lower bounds for your distribution graph and name them as "lower_bound" and "upper_bound". 4. Set the lower_bound of your graph to "mean - standard deviation". 5. Set the upper_bound of your graph to "mean + standard deviation". 6 . Create a sequence of 1000 values based on population mean and standard deviation and save it as "x". You can use: seq(-4, 4, length = 1000) * standard deviation + mean 7. Create a vector of values that shows the height of the probability distribution for each value in "x". Save this as "y" 8. Plot normal distribution using "x" and "y". 9. Customize your plot. 10. Attach the graph of the distribution to your report.B RStudio - 0 X File Edit Code View Plots Session Build Debug Profile Tools Help . . 8 8 9 Go to file/function Addins * Project: (None) .

Using just your moo data yalues, describe the shape of your distribution. 2. Discuss the symmetry of the graph including comparisons of the mean and the median. What does this say about people's nger lengths? 3. Add I12 to the mean and create a new distribution graph. Is the graph effected by the change of mean? Why? Include the pictures of both of the graphs side by side in your report. 4. Multiply standard deviation by 2 and create a new distribution graph. Is the graph effected by the change of standard deviation? Why? Include the pictures of both of the graphs side by side in your report. 5. Find the interval that contains the pinkey length within two standard deviations of your mean. 5. What percent of the data are within two standard deyiations of the mean? Round to two decimal places.
