Question 1181630
Here's how to find P70:

1. **Find the z-score:** P70 represents the 70th percentile. We need to find the z-score that corresponds to a cumulative probability of 0.70. You can use a z-table or a calculator with statistical functions for this. The z-score for 0.70 is approximately 0.52.

2. **Use the z-score formula:** The z-score formula is:

   z = (x - μ) / σ

   Where:
   * z is the z-score
   * x is the value we're looking for (P70)
   * μ is the mean (49.7)
   * σ is the standard deviation (25)

3. **Solve for x (P70):**

   0.52 = (x - 49.7) / 25

   Multiply both sides by 25:

   13 = x - 49.7

   Add 49.7 to both sides:

   x = 62.7

Therefore, P70 ≈ 62.7000
