The average thickness of books on a library shelf is 8.3 centimeters. The standard deviation is 0.6 centimeter. If 20% of the bo
jeka57 [31]

Answer:

8.8 cm

Step-by-step explanation:

-We know that the top 20% of the books are oversized.

-We therefore find the z-value of the top 20%:

z_{0.1}=8.4

#We substitute the z value in formula to solve X.

z=\frac{\bar  X-\mu}{\sigma}

Where

  • X is the minimum thickness of the book.

-Given \sigma=0.6 \ , \mu=8.3, the minimum thickness,X can be calculated as follows:

z=\frac{\bar  X-\mu}{\sigma}\\\\0.84=\frac{\bar X-8.3}{0.6}\\\\\bar X=0.84\times 0.6+8.3\\\\=8.804\approx 8.8\ cm

Hence, the minimum thickness of the oversized books is 8.8 cm
