The statistical model indicates that daily sales have a direct relationship with the cost of ingredients used and an inverse relationship with rainy days.

Option A: On a rainy day, if total sales are greater than expected compared to the cost of ingredients used, it may indicate discrepancies that could be a sign of employee theft. For instance, if ingredients are used but not reflected in the sales, it suggests that items might be missing (stolen).

Option B: On a sunny day, lower-than-expected sales compared to the cost of ingredients could indicate wastage but not necessarily theft.

Option C and D: Both scenarios where total sales and the cost of ingredients are higher or lower than expected do not specifically point to theft without additional context​​.
