Also Attaching the excel for this question.

1.The mean maximum temperature for the cities in South America was greater than that for the cities in Oceania.
Mean Max for South America = 32
Mean Max for Oceania = 27
TRUE

2. At least one city reporting fine weather had a maximum temperature less than 0°C.
None of the Cities with FINE weather has a maximum temerature less than 0. The lowest of the maximum tem for these fine weather cities is 5 degree for VAN
FALSE

3.For the Asian cities, the median minimum temperature was 12°C.
There are 8 Asian cities and their minimum temps listed in ascending order is: {-3,-3,3,3,21,22,24 and 26}
Median is the average of 4th and 5th terms (in this case 3 and 21) which is 12 degrees
Hence TRUE

1) Yes,Mean of max temperature for cities in South America=29+38+29/3=32
Mean of max temperature for cities in Oceania=25+29/2=27

2)No,All countries which are reporting fine weather have +ve max temperatures

3)Yes,Asian cities have minimum temperature as:26,-3,24,22,21-3,3,3

So rearranging them :

-3,-3,3,3,21,22,24,26 so median is (21+3)/2=12°C

1. The mean maximum temperature for the cities in South America was greater than that for the cities in Oceania.

The mean maximum temperature for the cities in South America : (29+38+29)/3 = 32°C.

The mean maximum temperature for the cities in Oceania: (29+25)/2 = 27.5°C.
;
Thus its clear that the mean max temp for cities of South America is > mean max temp for cities of Oceania.

2. At least one city reporting fine weather had a maximum temperature less than 0°C.
It can be very easily inferred from the passage that no city with a fine weather had a max temp. < 0°C.

3.For the Asian cities, the median minimum temperature was 12°C.
Now arranging the minimum temperature of Asian cities in ascending order we get: -3, -3, 21, 22, 3, 3, 24,26.
Since there are even no. of cities median = (21+3)/2 = 12°C.

Re: The table lists minimum temperature, maximum temperature, an [#permalink]
Official Explanation

The mean maximum temperature for the cities in South America was greater than that for the cities in Oceania.

Sorting on Continent reveals that, when temperatures are measured in °C, the mean maximum temperature for the 3 cities listed in South America was 1/3 (29 + 38 + 29), or 32, while the mean maximum temperature for the 2 cities listed in Oceania was 1/2 (25 + 29), or 27. Since 32 > 27, the mean maximum temperature for the cities in South America was greater than that for the cities in Oceania.

At least one city reporting fine weather had a maximum temperature less than 0°C.

Sorting on Weather conditions reveals 7 cities reporting fine weather, for which the least maximum temperature reported was 5°C. Thus none of the 7 cities reported a maximum temperature less than 0°C.

For the Asian cities, the median minimum temperature was 12°C.

Sorting on Continent reveals that there are eight Asian cities listed. When the minimum temperatures for the eight cities are ordered from least to greatest, the median minimum temperature is equal to the arithmetic mean of the fourth and fifth temperatures in the list. Using the Continent sort, the first five temperatures in the list (in °C) are -3, -3, 3, 3, and 21, so the median minimum temperature is therefore 12
