Final answer:
In a Normal distribution, the shaded area represents the probability of x being less than or equal to a specific value. Without more context like the standard deviation or the exact positioning of the shaded area, one must assume based on whether the shaded area is to the left of 48 or 52 to determine the correct option.
Step-by-step explanation:
The shaded region under a Normal distribution with a mean of 52 would represent the probability of random variable x being less than or equal to a particular value. To determine which statement is best, a comparison between Probability of x≤52 and Probability of x≤48 is required. To find these probabilities, one would use normal distribution tables or a calculator with the mean (52 in this case) and the appropriate standard deviation. If the shade is to the left of 52, then it is more likely referring to Probability of x≤52. If the shaded region includes values less than 48, the statement Probability of x≤48 would be more accurate. Specific details like the position of the shaded area on the graph and the standard deviation would provide more context to solve this problem precisely.
