The table presents data on the 11 U.S. coastal counties that were hit by the most hurricanes between 1960 and 2008. It also lists the percent change in population for each county during the same time period. Positive percentages represent population growth.

Consider the following statements. For each statement, evaluate whether that statement is True or False, according to the information in the table.
True False
The median number of hurricanes in the Florida counties was higher than the median number of hurricanes in each of the other states’ counties.
The counties listed in the table that experienced the three greatest percent changes in population during the period are all part of the coastline region whose listed counties had the greater range in number of hurricanes during the same period.
The Gulf of Mexico coastline region experienced fewer hurricanes per county listed in the table, on average, than did the Atlantic coastline region.

1. The median number of hurricanes in the Florida counties was higher than the median number of hurricanes in each of the other states’ counties.

No. of hurricanes in Florida counties - 11,12,15
Median => 12

No. of hurricanes in Louisiana counties - 11,11,11,12,14
Median => 11

No. of hurricanes in North Carolina counties - 13,13,14
Median => 14

Clearly, the median number of hurricanes in the Florida counties was NOT higher than the median number of hurricanes in each of the other states’ counties.

False

2. The counties listed in the table that experienced the three greatest percent changes in population during the period are all part of the coastline region whose listed counties had the greater range in number of hurricanes during the same period.

Counties that experienced the three greatest percent changes in population during the period - Dare County, Palm Beach County, Miami-Dade County. All these 3 counties belong to the Atlantic coastline region.

Basically, the question stem is whether counties belonging to the Atlantic coastline had a greater range in the number of hurricanes than counties belonging to the Gulf of Mexico coastline?

Coastline region and its Range
Atlantic =>14-11 = 3
Gulf of Mexico =>15-11 = 4

False

3. The Gulf of Mexico coastline region experienced fewer hurricanes per county listed in the table, on average, than did the Atlantic coastline region.

Total number of hurricanes experienced by the Gulf of Mexico coastline region - 73
The average number of hurricanes per county - 74/6 => 12.3

Total number of hurricanes experienced by the Atlantic coastline region - 63
The average number of hurricanes per county - 63/5 => 12.5

(TRUE/FALSE) The median number of hurricanes in the Florida counties was higher than the median number of hurricanes in each of the other states’ counties.

1. Median (3 x Florida counties) = 12 (11,12,15)
2. Median (5 x Gulf of Mexico counties) = 11 (11,11,11,12,14)
3. Median (3 x Atlantic Counties) = 13 (13,13,14)

While median number of hurricanes in the Florida counties was higher than the median number of hurricanes in Gulf of Mexico, the same is Not True when it is compared against the median number of hurricanes in counties at Atlantic.

FALSE

(TRUE/FALSE) The counties listed in the table that experienced the three greatest percent changes in population during the period are all part of the coastline region whose listed counties had the greater range in number of hurricanes during the same period.

The the three greatest percent changes in population during the period are all part of the Atlantic coastline region (ie, Dare County, Palm Beach County and Miami-Dade County).

also,

Range in number of hurricanes during the same period for Atlantic Coastline region = 14-11 = 3 (lower range)

Range in number of hurricanes during the same period for Gulf of Mexico Coastline region = 15-11 = 4 (higher range)

FALSE

(TRUE/FALSE) The Gulf of Mexico coastline region experienced fewer hurricanes per county listed in the table, on average, than did the Atlantic coastline region.

Average hurricanes / county (for Atlantic Region) = 13+14+11+12+13 = 63/5 = 12 3/5
Average hurricanes / county (for Gulf of Mexico Region) = 11+11+15+14+11+12 = 74/6 = 12 1/3

Clearly, the Gulf of Mexico coastline region experienced fewer hurricanes per county, on an average basis.

TRUE
