Consider the following situation and data for the entire quiz. It is desired to explore the relationship between test 2 score (out of 100) and score on the final (out of 150). For the data below, assume TEST 2 (X) is the natural explanatory variable and FINAL (Y) is the response variable in this situation.

col1 X 96 83 80 77 94 95 69 91 90 99 86 80 74 85 72
col2 Y 138 125 120 115 140 145 100 142 138 147 135 128 120 132 118

1. Sketch a scatterplot for this data.
2. Computer the best fitting line for this data and graph it on the plot above. Give all calculations.
3. Find the correlation coefficient giving all calculations. What does it indicate about the strength of the linear relationship between X and Y?
4. Predict a person's score on the final when their test 2 score was 78,

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
