### Question Description

Consider the following frequency distribution:

 Class No. Class Boundaries Frequency 1 8087.5 - 8096.5 3 2 8096.5 - 8105.5 8 3 8105.5 - 8114.5 10 4 8114.5 - 8123.5 14 5 8123.5 - 8132.5 15

The skewness of the  frequency distribution is Student has agreed that all tutoring, explanations, and answers provided by the tutor will be used to help in the learning process and in accordance with Studypool's honor code & terms of service. Skewness calculator Formula:

`	 g=sum(x-xmean)^3 for all observations/(n-1)^3`
where:
x: Mean of samples
xi:The ith sample
n: Total sample number
s: Standard Deviation of all samples
g: Sample skewness

Here data: 3,8,10,14,15

n = 5

mean = (3+8+10+14+15)/5 = 10

variance = 23.5

standard deviation = sqrt(23.5) =4.847

Putting these values in skewness formula, we get skewness = -0.3555 nxpu2002 (27)
