Answer #1

Step 1 : Enter data in excel in a single column

Step 2 : calculate five number summary for that use function

Minimum = QUARTILE.INC(data range, 0)

Quartile 1 =QUARTILE.INC(datarange,1)

Quartile 2 =QUARTILE.INC(datarange,2)

Quartile 3 =QUARTILE.INC(datarange,3)

Maximum =QUARTILE.INC(datarange,4)

So we get excel output

Therefore,

We get

Q3 - Q2 = 6

Q2 - Q1 = 6

We get

Q3 -Q2 = Q2 - Q1

Hence shape of distribution is symmetric distribution.

Thank you!
