Question

this distribution is positively skewed. alternate answer: the coefficient of skewness is 1.5. this distribution is positively skewed. part 2 of 4 (b) mean = 37, median = 34, standard deviation = 5 the coefficient of skewness is 1.8. this distribution is positively skewed. part: 2 / 4 part 3 of 4 (c) mean = 17.8, median = 17.8, standard deviation = 1.1 the coefficient of skewness is. this distribution is select.

Explanation:

Step1: Apply skewness formula

Use Pearson's coefficient of skewness: $S_k = \frac{3(\text{Mean} - \text{Median})}{\text{Standard Deviation}}$
Substitute values: $S_k = \frac{3(17.8 - 17.8)}{1.1}$

Step2: Calculate the coefficient

Simplify the numerator first: $17.8 - 17.8 = 0$, so $S_k = \frac{3 \times 0}{1.1} = 0$

Step3: Classify distribution type

A skewness coefficient of 0 means the distribution is symmetric.

Answer:

The coefficient of skewness is 0.
This distribution is symmetric.
