in this problem, which of the following statements is true?
select the correct response:
the lower bound is -9e-99
the lower bound is 1028.
the 90th percentile score is located on the left side of the mean.
the 90th percentile score is located on the right side of the mean.
the area of no interest to the problem solver is less than half of the curve.
the upper bound is -9e99.
my answer is not listed among the given choices.
the upper bound is 92.
the 90th percentile occupies more than half of the curve.

Explanation:

In a normal distribution, the mean represents the 50th percentile. Percentiles above 50 fall to the right of the mean, as they represent scores higher than the average. The 90th percentile is higher than the 50th percentile, so it lies on the right side of the mean.

Answer:

The 90th percentile score is located on the right side of the mean.
