Question

Use the frequency distribution shown below to construct an expanded frequency distribution. High Temperatures (°F) Class 15-25 26-36 37-47 48-58 59-69 70-80 81-91 Frequency, f 18 41 66 67 84 66 23 Complete the table below. High Temperatures (°F) (Round to the nearest hundredth as needed.) Class Frequency, f Midpoint Relative frequency Cumulative frequency 15-25 18 20 0.05 18 26-36 41

          Use the frequency distribution shown below to construct an expanded frequency distribution.
