Question

the histogram shows the weekly rates charged by different daycares for a 2-year-old child. weekly daycare cost histogram: y-axis number of daycares, x-axis weekly cost (dollars) from 100 to 300. which phrase describes the daycare cost data?
○ left-skewed
○ right-skewed
○ nearly symmetrical
○ primarily asymmetrical

Explanation:

To determine the skewness of the daycare cost data from the histogram, we analyze the distribution's shape. A left - skewed distribution has a longer tail on the left, a right - skewed one has a longer tail on the right, and a nearly symmetrical distribution has a shape that is roughly balanced around the center.

Looking at the histogram, the bars increase in height up to a peak (around 180 - 200 dollars) and then decrease in a relatively symmetric way on both sides of the peak. The left side (lower cost) and the right side (higher cost) of the peak have a similar pattern of bar heights decreasing. There is no long tail on either the left or the right that would indicate a strong skew. So the data is nearly symmetrical.

Answer:

nearly symmetrical
