The image contains a frequency distribution table showing the time (in minutes) required to pack 128 packages, followed by several statistical questions related to skewness and kurtosis. Here is a breakdown of the task:

**Table:**
- **Time (Minutes):** 
  - 0.5 - less than 1.0
  - 1.0 - less than 1.5
  - 1.5 - less than 2.0
  - 2.0 - less than 2.5
  - 2.5 - less than 3.0
  - 3.0 - less than 3.5
- **Frequency (Jumlah Paket):** 
  - 5, 12, 25, 36, 30, 20
- **Total Packages:** 128

**Questions:**
a. Calculate Pearsonian Coefficient of Skewness.  
b. Calculate Quartile Coefficient of Skewness (Bowley).  
c. Find Moment Coefficient of Skewness.  
d. Find Moment Coefficient of Kurtosis.  
e. Calculate Quartile Coefficient of Kurtosis.  
f. Draw conclusions from the results.

To proceed with the calculations:

1. **Pearsonian Coefficient of Skewness** is given by:
   \[
   \text{Skewness} = \frac{3(\text{Mean} - \text{Median})}{\text{Standard Deviation}}
   \]

2. **Quartile Coefficient of Skewness (Bowley)**:
   \[
   \text{Skewness} = \frac{Q_3 + Q_1 - 2Q_2}{Q_3 - Q_1}
   \]

3. **Moment Coefficient of Skewness**:
   \[
   \gamma_1 = \frac{\mu_3}{\sigma^3}
   \]
   Where \(\mu_3\) is the third central moment.

4. **Moment Coefficient of Kurtosis**:
   \[
   \gamma_2 = \frac{\mu_4}{\sigma^4}
   \]
   Where \(\mu_4\) is the fourth central moment.

5. **Quartile Coefficient of Kurtosis** would require calculation of the quartiles and moments.

I can begin the calculation by determining the mean, median, quartiles, variance, and central moments from the table data. Do you want me to go step by step through the first calculation, or proceed with a specific question?
