1. Calculate the decrease in cholesterol:
   $$
   \text{Decrease} = 202 - 178 = 24 \, \mathrm{mg/dl}
   $$

2. Find the percent decrease:
   $$
   \text{Percent decrease} = \left(\frac{24}{202}\right) \times 100
   $$

3. Use a calculator:
   $$
   \frac{24}{202} \approx 0.1188
   $$
   $$
   0.1188 \times 100 \approx 11.88\%
   $$

4. Round to the nearest tenth:
   $$
   11.88\% \approx 11.9\%
   $$

Final answer:
$$
11.9\%
$$
The cholesterol decreased by 11.9%.
