Question

D Question 2 Please use the words contained within the parentheses to describe the following: 1. Skew (negative, normal, positive) 2. Kurtosis (leptokurtic, mesokurtic, platykurtic) Question 3 1 pts 1. Compute the value used to evaluate the normality assumption 2. Is the normality assumption violated (Yes/No) ace

mean:19.6

median:17

std. deviation: 8.235

variance:67.822

skew value:2.147

kurtosis:6.134

Answer 1

Question 2

1) Mean = 19.6

Median =17

Here mean is greater than Median

So it is positively skewed

Also skewness = 2.147 which is greter than 1.

So it is positively skewed.

Skew : Positive

2)

Here kurtosis = 6.134

Kurtosis is greater than 3

So it is leptokurtic

Kurtosis: Leptokurtic
