1. \text{Round the given values to one decimal place:}

\mu_1 = 938.19 \approx 938.2

\mu_2 = 18.0406 \approx 18.0

s = 94.282 \approx 94.3

2. \text{Use the formula for effect size:}

d = \frac{\mu_1 - \mu_2}{s}

d = \frac{938.2 - 18.0}{94.3} = \frac{920.2}{94.3} \approx 9.8

3. \text{Interpret the effect size:}

\mu_1 > \mu_2 \Rightarrow \text{Effect size is positive.}

\text{Answer: Effect size} = 9.8 \text{ (positive)}
