17. Reports from a new system set up to monitor internet use by computer employees. indicate that 145 out of a random sample of 1100 employees at a corporation accessed internet sites that were clearly not related to their jobs over the last week. On average, employees who accessed non-job related sites pent 4.8 hours per week at such sites with a standard deviation of 2.1 hours.
a.) Give a 95% confidence interval for the percentage of employees at the corporation who access non-job related sites.
b.) Briefly explain in one short sentence how to interpret this interval
c.) Statistics show that 10% of people nationwide access non-job related sites at work. Is this company really any different from the national statistics?
d.) Can we say that roughly 95% of people at this company spent in the range of 4.8 hours plus or minus 4.2 hours on non job-related web sites?

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
