Good day, this problem is already reposted. Pls answer question 4 this time. Since it is related to question 1, the answer for it is also provided below. Tysm.

**

A random sample was taken of the thickness of insulation in transformer windings, and the following thicknesses in millimeters were recorded:


1. a) Make a frequency table for these data starting at lowest lower class limit of 20 and with a class width/ class size of 7.

 b) Determine the class marks, class boundaries, relative frequency, <CF, and >CF.
Note: You can use EXCEL.

 

✓✓ 4. From question 1: Using the frequency distribution, describe the shape in terms of its skewness and kurtosis (calculate/compute SK and K).
