The heights of children 2 years old are normally distributed with a mean of 32 inches and a standard deviation of 1.5 inches. pediatrician regularly measure the heights of toddlers to determine whether there is a problem. pediatrician determines that there may be a problem when a child is in the top or bottom of 5% heights. what is the height of a 2 year old that could be a problem

The problematic heights are those lower than 29.5325 inches and higher than higher than 34.4675 inches

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean and standard deviation , the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

Pediatrician determines that there may be a problem when a child is in the top or bottom of 5% heights.

Bottom 5%

Any height lower than the value of X when Z has a pvalue of 0.05. So

A height lower than 29.5325 inches is problematic.

Top 5%

Any height higher than the value of X when Z has a pvalue of 0.95. So

A height higher than 34.4675 inches is problematic.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
