Scenаriо A: Mоbile Orders A retаiler knоws thаt 40% of all of its online orders are placed on a mobile device. A random sample of 150 orders is selected from the millions of orders in its database, and the sample proportion of mobile orders, p̂, is recorded. The sampling distribution of p̂ is shown below. Find the probability that the sample proportion is greater than 0.46 (the shaded region). Show the z-score and use the z-table to find the probability.
