Q. Complete the statement. Round your answer to the nearest thousandth.In a population that is normally distributed with mean 34 and standard deviation 6, the bottom 70% of the values are those less than ___.
Find z-score for 70\%: Find the z-score for 70%.Using a z-table or calculator, the z-score for 70% is approximately 0.524.
Use z-score formula: Use the z-score formula to solve for X. mean (μ): 34 standard deviation (σ): 6 z-score (Z): 0.524 Z=σX−μ 0.524=6X−34
Multiply to isolate X: Multiply both sides by the standard deviation to isolate (X−μ).0.524×6=X−343.144=X−34
Add mean to solve: Add the mean to both sides to solve for X.X=3.144+34X=37.144
Round the answer: Round the answer to the nearest thousandth. X≈37.144
