Use technology or a z-distribution table to find the indicated area. the ages of visitors to a theme park are normally distributed with a mean of 15 years and a standard deviation of 5.2 years. approximately 70% of the visitors to the theme park are older than which age? 11.4 12.3 17.7 18.6

Approximately 70% of the visitors to the theme park are older than about 12.3.

A z-score of about -0.53 is position on the normal distribution for finding the amount above 30% (70%).

Therefore, we can write and solve the following equation:

(x - 15) / 5.2 = -0.53
x - 15 = -2.756
x = 12.244

The closest amount is 12.3.
