2) For each of the scatterplots below, CIRCLE the words that most correctly describe the corresponding plots related to type (linear or non-linear), correlation (positive, negative, none), and strength (weak, moderate, strong) a) Circle the best answers for i),i) and ii) ) Linear OR non-linear )Positive OR negative OR neither ii)Strong OR moderate Or weak b) Circle the best answers for i),ii) and iii) i)Linear OR non-linear ii)Positive OR negative OR neither iii)Strong OR Moderate Or weak

It is generally believed that there is a relationship between a college’s acceptance rate and its graduation rate. I wanted to know how strong this relationship is within the top universities in the country so I collected the graduation rate and acceptance rate data of a randomly selected sample of universities from all the top U.S. universities (with an acceptance rate at or below 30%). The data set is in Tab Q2 of the Excel data file. a.) Create a scatter plot between the two variables using Excel. Paste the plot here and format it into an APA-styled “figure” (see Assignment Guides for APA format).Be sure to submit the Excel file that you used to create the scatter plot.     b) Calculate the mean and standard deviation for the two variables separately.   c) Calculate the Z scores for all the scores of the two variables, separately.Tips: It may help to prevent error and to increase clarity if the process and/or the answers (z scores) are listed in a table format.     d) Calculate…

B) has more than one answer .. Thank you

4.3) •VA report from Texas Transportation Institute (Texas A&M University System 2005) on Congestion Re- duction Strategies looked into the extra travel time (due to traffic congestion) for commute travel per traveler per year in hours for different urban areas. Below are the data for urban areas that had a population of over 3 million for the year 2002. Extra Hours per Traveler per Year Urban Area Los Angeles San Francisco 98 75 Washington DC Atlanta 66 64 Houston 65 Dallas, Fort Worth Chicago Detroit 61 55 54 Miami 48 Boston 53 New York 50 Phoenix 49 Philadelphia 40 4. Compute the mean and median values for extra travel hours. Based on the values of the mean and median, is the distribution of extra travel hours likely to be approximately symmetric, positively skewed, or negatively skewed?

The ages of employees at two local restaurants are listed in order. Restaurant A - 21, 21, 23, 25, 26, 27, 30, 34 Restaurant B - 23, 25, 25, 25, 26, 27, 27, 30 Determine the difference between the mode in these two data sets. Use the keypad to input your answer. The difference in mode between the two data sets is

Consider this set of data: 4.5 3.2 3.5 3.9 3.5 3.9 4.3 4.8 3.6 3.3 4.3 4.2 3.9 3.7 4.3 4.4 3.4 4.2 4.4 4.0 3.6 3.5 3.9 4.0 Construct a stem and leaf plot by using the leading digit as the stem. Construct a stem and leaf plot by using each leading digit twice. Does this technique improve the presentation of the data? Explain.
