Answer 1

send the data First

please mark me as brainliest

Answer 2

Answer:

Step 1: Subtract the mode from the mean: 70.5 – 85 = -14.5. Step 2: Divide by the standard deviation: -14.5 / 19.33 = -0.75.

...

Sample problem: Use Pearson's Coefficient #1 and #2 to find the skewness for data with the following characteristics:

Mean = 70.5.

Median = 80.

Mode = 85.

Standard deviation = 19.33.
