**Normal Distribution of Test Scores**The test scores for the analytical writing section of a particular standardized test can be approximated by a normal distribution, as depicted in the figure.### Questions(a) What is the maximum score that can be in the bottom 20% of scores?(b) Between what two values does the middle 60% of scores lie?### Diagram ExplanationThe diagram presents a normal distribution curve of test scores. The mean (μ) of the distribution is 3.5, and the standard deviation (σ) is 0.84. The x-axis represents the score range, which extends from 1 to 6. Vertical lines on the curve indicate the spread of the scores around the mean.### Answer Section(a) The maximum score that can be in the bottom 20% is ________. (*Round to two decimal places as needed.*)

It is given that the mean is 3.5 and the standard deviation is 0.84.
