The image presents a problem involving a normal distribution, specifically \( N(400, 23) \). The task is to find the \( x \) value corresponding to a shaded area under the curve. The normal distribution curve is shown with a mean (\( \mu \)) of 400 and a standard deviation (\( \sigma \)) of 23. The left tail of the curve, representing 5% (0.05) of the area, is shaded. The goal is to find the \( x \) value that corresponds to the lower 5% of the distribution.Below the diagram, a multiple-choice question is provided with the following options for the \( x \) value:- 362.2- 355.7- 3791- 3476The reader is required to select the correct \( x \) value from these options based on their understanding of the normal distribution and related calculations.
