I. 4, 9, 0/22 Question 1 of 8, Step 1 of 3 Correct The following stem-and-leaf plot represents the distribution of weights for a group of people. Stem Leaves 8 3 3 3. 6. 9. 10 3 4 4. 4. 11 3 3 6 9 12 2 3 5 5 8 13 3 14 1 9. 15 56 16 3 3 4 Key: 8|2 = 82 pounds %3D Step 1 of 3: What is the weight of the lightest person in the group?

I need help calculating the population size (n), sum, mean, median, mode, range, std. deviation and coef. of variation.

Step 4 The following table summarizes the given data and the forecast values. There will not be a forecast error for the first month. Complete the columns for the forecast error and squared forecast error. Month Value Forecast Value 1 2 3 4 5 6 7 19 27 23 28 24 23 28 19 23 23 24.25 24.2 24 Forecast Error Actual - Forecast Submit Skip (you cannot come back) 27 19 = 8 0 5 -0.25 4 Total Squared Forecast Error (Actual - Forecast)² (8)² = 64 0 1.44 The MSE will be the average of the squared forecast error column. Find the average of this column, rounding the result to two decimal places. MSE =

Questions 1 and 2 use the X and Y data below.  You can think of this data as representing the heights of 5 individuals (labelled A,B,C,D,E) at ages 11 (X column)  and 12 (Y column). Obs  X           Y           Paired Y-X A 60 62   B 61 62   C 62 63   D 63 64   E 64 66   The means and variances for X and Y are shown below. (You can verify to practice calculation steps.)   X Mean: 62, X Variance: 2.5     |    Y Mean: 63.4, Y Variance: 2.8 The Y - X difference column has not been computed.  You need to fill this out and compute the corresponding mean and variance (for Y-X) for question 2 1) Test whether the population mean of Y is no greater than 1/2 (0.5) unit higher than the population mean for X as the null hypothesis (Ho) vs the population mean of Y is more than 1/2 unit greater than the population mean for X as the alternative hypothesis (H1).  What is the small sample t statistic for the test of Ho?  Round to two decimal places (e.g., 1.23) Assume the measurements…
