1. Between 1953 and 2020, 38 hurricanes have made landfall on Canadian soil. The hurricanes are often downgraded by the time they reach Canada; however, at their strongest force, they receive a category rating to determine the maximum size and intensity of the storm of either Tropical, 1, 2, 3, 4, or 5. Five represents the largest and most ferocious storms, with the title of Tropical given to downgraded storms that more commonly impact Canada.^[1] The table below depicts hurricanes at their peak strength before impacting Canada. Use the given data to create a table with columns for frequency, relative frequency, and cumulative frequency for each category of hurricane.
