Answer

Final Answer: The data value corresponding to z=0.36 is 63.3.

Steps

Step 1 :We are given a normal distribution with mean μ=65.1 and standard deviation σ=4.93. We are asked to find the data value corresponding to the z-score z=0.36.

Step 2 :The z-score is a measure of how many standard deviations an element is from the mean. The formula for the z-score is z=xμσ, where x is the data value we are trying to find.

Step 3 :We can rearrange this formula to solve for x: x=zσ+μ.

Step 4 :Substituting the given values into this formula, we get x=0.364.93+65.1.

Step 5 :Calculating the above expression, we get x=63.325199999999995.

Step 6 :Rounding to the nearest tenth as needed, we get x=63.3.

Step 7 :Final Answer: The data value corresponding to z=0.36 is 63.3.
