duction: In this learning lab, we will continue to work with the data on baby looking times that we used in the previous learning lab. To look at the data, open the file PSYCH200_Lesson_4_Learning_Lab.xls with Excel. You should see a dataset for variable X in column A. In total, the dataset contains 20 values. Assignment: For the dataset, generate the formulas for the following statistics: The mean value of X, put the formula in cell D2. The standard deviation of X, put the formula in cell D3. The z-score for a given input value specified in cell D6 to be computed against the data for variable X. Put the formula for the z-score in cell D9. After you have generated these formulas, enter the z-scores you find for evaluated values 1 to 8 (listed in column F) when you input them in cell D6, the evaluated value. Enter the results in column G (use the cell that corresponds to the inputted value listed in the same row in column F). Finally, complete the statement in cell I1 by typing your answer in cell I2. You should not need to use more than two sentences. Save your work X 5 6 3 7 8 3 4 2 3 3 4 6 2 5 3 2 2 5 2 3 Mean of X = standard deviation of X = Value to be evaluated: Z-score 1 Evaluated value 1 2 3 4 5 6 7 8 Z-score The value for z changes sign between X = 3 and X = 4 because
