Question

number of days
temperature (°f)
which comparison of the distributions is true?
the distribution of low temperatures is nearly symmetric, and the distribution of high temperatures is nearly symmetric.
the distribution of low temperatures is skewed right, and the distribution of high temperatures is nearly symmetric.
the distribution of low temperatures is nearly symmetric, and the distribution of high temperatures is skewed right.
the distribution of low temperatures is skewed right, and the distribution of high temperatures is skewed right.

Explanation:

Step1: Analyze low - temperature distribution

Looking at the bar - graph for daily lows, the frequencies start low, increase to a peak around 15 - 20°F, and then decrease. The tail on the right side (higher temperatures) is longer than the left side. So, it is skewed right.

Step2: Analyze high - temperature distribution

For daily highs, the frequencies are more evenly distributed around the middle values (30 - 35°F and 35 - 40°F). The distribution is approximately symmetric.

Answer:

The distribution of low temperatures is skewed right, and the distribution of high temperatures is nearly symmetric.
