Step 1 :Given that the amount of syrup that people put on their pancakes is normally distributed with a mean of \(60 \mathrm{~mL}\) and a standard deviation of \(8 \mathrm{~mL}\).
Step 2 :We are asked to find the probability that a single randomly selected individual consumes between \(56.6 \mathrm{~mL}\) and \(61.4 \mathrm{~mL}\) of syrup.
Step 3 :To solve this, we can use the Z-score formula to standardize the values and find the corresponding probabilities from the standard normal distribution.
Step 4 :The Z-score for the lower bound \(56.6 \mathrm{~mL}\) is calculated as \(-0.425\).
Step 5 :The Z-score for the upper bound \(61.4 \mathrm{~mL}\) is calculated as \(0.175\).
Step 6 :Using the standard normal distribution, we find the probability that a single randomly selected individual consumes between \(56.6 \mathrm{~mL}\) and \(61.4 \mathrm{~mL}\) of syrup is approximately \(0.2340\).
Step 7 :Thus, the final answer is \(\boxed{0.2340}\).
