Answer

Explanation:

Step1: Analyze frequency distribution

We have the frequency distribution of hours of sleep.

Step2: Create histogram conceptually

For a histogram, the x - axis represents hours of sleep and the y - axis represents frequency. Bars are drawn for each hour of sleep value with height equal to its frequency.

Step3: Determine distribution shape

The frequencies increase from 4 hours of sleep to 8 hours of sleep and then decrease. The tail on the left (lower hours of sleep) is shorter and the tail on the right (higher hours of sleep) is longer. So, it is skewed to the right.

Answer:

  1. To create a histogram: On the x - axis, mark the values 4, 5, 6, 7, 8, 9, 10, 11 representing hours of sleep. On the y - axis, mark the frequency values. Draw bars for each x - value with height equal to the corresponding frequency (e.g., for x = 4, height of bar = 2; for x = 5, height of bar = 3 and so on).
  2. Skewed to the right.
