Question Number 2. See attachment.

pmhetical Data Set Below you will find your mock data sets. In addition to the questions raised below you may use any of the data provided in the below data sets for any descriptive statistics calculations. You may use excel but please show your calculations for any techniques (You do not have to manually calculate a simple regression). Please remember to tell me what the result is and what it means. Question: What is the difference in turnover rates between corporations that have learning &development departments compared to those that do not? 1. Imagine there was a measure for quality of the companies learning and development department that used a 100-point scale and you wanted to understand how your company compares to what you know is the average across the industry. You collected a random sample, which produced the sample below (hypothesis data). You know the average mean for the population score across the industry is about 75.0. Is your sample different from the population at an alpha of .05? 2. You are also interested in the likelihood (probability) of getting a score above 80 and below 60 from the hypothesis data set. 3. To understand the correlation between L&D department quality and retention you also collected the below data (Correlation Sample) what is the correlation between your variables? 4. Finally, you are curious about doing a simple regression using the (correlation data set). Is this a good sample to run a regression? What does the regression tell you? (You may do the regression in excel) Correlation Sample Quality of Likelihood learning and to stay development (retention) I'O rams p g -- - .- - - - --- n.- n \"- - --- --- -- -- -- - n \"- \"- -- -- - .- \
