Answer

The probability that \( x \) lies between 7 and 16 is **0.450**.

Solution

Let's solve part (d) using the properties of a uniform distribution. **Uniform Distribution Basics:** - **Range:** The uniform distribution is defined from \( a = 5 \) to \( b = 25 \). - **Probability Density Function (PDF):** \( f(x) = \frac{1}{b - a} = \frac{1}{25 - 5} = \frac{1}{20} = 0.05 \) **Part (d): Find the probability that \( x \) lies between 7 and 16.** 1. **Determine the Interval Length:** \[ \text{Interval Length} = 16 - 7 = 9 \] 2. **Calculate the Probability:** \[ P(7 \leq x \leq 16) = \frac{\text{Interval Length}}{b - a} = \frac{9}{20} = 0.45 \] 3. **Round to Three Decimal Places:** \[ P(7 \leq x \leq 16) = 0.450 \] **Answer:** (d) The probability that \( x \) lies between 7 and 16 is **0.450**.

The Deep Dive

To find the probabilities for the uniform distribution from \( a = 5 \) to \( b = 25 \), we can use the formula for the probability of an interval \( (x_1, x_2) \): \[ P(x_1 \leq X \leq x_2) = \frac{x_2 - x_1}{b - a} \] where \( b - a \) is the length of the entire distribution. **(a)** You already calculated \( P(6 \leq x \leq 15) \) as 0.450, which is correct! **(b)** For \( P(11 \leq x \leq 24) \): \[ P(11 \leq x \leq 24) = \frac{24 - 11}{25 - 5} = \frac{13}{20} = 0.650 \] **(c)** For \( P(9 \leq x \leq 23) \): \[ P(9 \leq x \leq 23) = \frac{23 - 9}{25 - 5} = \frac{14}{20} = 0.700 \] **(d)** For \( P(7 \leq x \leq 16) \): \[ P(7 \leq x \leq 16) = \frac{16 - 7}{25 - 5} = \frac{9}{20} = 0.450 \] So, the probability that \( x \) lies between 7 and 16 is **0.450** (rounded to three decimal places).
