Answer to Problem 21E

The normal distribution curve is wrong placed due to which the wrong probability x -value is resulted.

Now, the correct x -value is 68.26% and it is shown by the following figure:

Explanation of Solution

Given information:

  Big Ideas Math A Bridge To Success Algebra 2: Student Edition 2015, Chapter 11.1, Problem 21E , additional homework tip  3

  μ=25σ=2

Here, in the given calculation of the figure, understands that

  P(23x27)=P(μ2σxμ+2σ)P(23x27)=13.5%+34%+34%+13.5%P(23x27)=95%

So, the error of the given problem is x value between 2 and 7 that means you need to keep difference of the standard deviation in the normal distribution curve. But from the figure, the deviation is observed as 1 .

Now, the correct method of the estimation of probability:

  P(23x27)=P(23252xμσ27252)P(23x27)=P(1xμσ1)

Use the standard normal table:

  P(23x27)=0.6826=68.26%

The probability that P(23x27)=68.26% is equal to the shaded area under the curve as:
