1. Create a stemplot for Islamic financial literacy rates
2. Based on your answer in question (a), is this stemplot following normal distribution curve, right-skewed, or left-skewed? Explain you reason(s)
3. Calculate the mean (average) value of Islamic financial literacy rate
4. Sort the data from low to high and calculate the location for 25^th percentile (Q1), the 50^th percentile or median (Q2), and the 75^th percentile (Q3)
