Final answer:
Without specific details of the inequality model mentioned in the question, we cannot ascertain the correct solution set. The information provided is unrelated to the specifics of the inequality or its solution set, and therefore does not aid in choosing between options A, B, C, or D.
Step-by-step explanation:
The information provided does not seem to contain enough data to determine a specific inequality or its solution set. In a general sense, when we are given a range such as 1.5 ≤ x ≤ 4.5, it implies that x can be any number within that range inclusively. However, there is no direct mention of the solutions x ≤ −5, x ≤ 5, x ≤ 1, or x ≤ −14 in the data provided. Additionally, references to linear equations or distributions in the provided information do not have enough context to determine the solution set of an inequality.
If we were to look at the example of normal distribution, where x = −5 and z = −3.14, we can surmise that the value of x is below the mean of the distribution, but again this does not directly answer the question about the inequality's solution set.
