Consider the following frequency table representing the distribution of the length of a morning walk with the dog (in miles). Determine the midpoint for the fourth class.

Answer

To determine the midpoint of a class, you add the lower limit and the upper limit of that class together and then divide by 2. The formula for it is: Midpoint = (Lower Class Limit + Upper Class Limit) / 2. Based on the frequency table provided: The first class is 0.23-0.31. The second class is 0.32-0.40. The third class is 0.41-0.49. The fourth class is 0.50-0.58. Identify the limits for the fourth class: Lower limit = 0.50, Upper limit = 0.58. Now, calculate the midpoint: Midpoint = (0.50 + 0.58) / 2 = 1.08 / 2 = 0.54. Therefore, the midpoint for the fourth class is 0.54.
