Suppose \(X\) represents the delivery time (in minutes) of pizzas from a local shop, and it follows a normal distribution with a mean of 25 minutes and a standard deviation of 5 minutes. The shop guarantees a delivery deadline such that 90\(\pourcent\) of orders are delivered before this time. Using a
