the mean of the chocolate chip column is 938 19 and the mean of the bag weight is 18 0406 round these to one decimal place

Question

The mean of the chocolate chip column is 938.19 and the mean of the bag weight is 18.0406. Round these to one decimal place. The standard deviation is 94.282. Round this to one decimal place also. With all of these numbers, what is the effect size of the study? And is it positive or negative? Thanks

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)}
