Anthropologists collected data about cultural patterns and norms for several small indigenous populations in various countries. The table displays data collected about the economic base; residential patterns (residence); degree of market integration (mean MI)—defined as the percentage of calories obtained in the marketplace; percentage of population participating in world religions (mean WR); and average community size (mean CS).

For each of the following statements about these indigenous populations, select  Yes  if the statement accurately reflects the data provided in the table. Otherwise, select  No .

Official Explanation

The populations that forage have the lowest market integration ratings.

Each of the populations that depend on both farming and wage work is sedentary and has a mean community size among the five largest.

The range for market integration is less than the range for participation in world religions.

To determine the range for market integration, sort the table on Mean MI. The maximum market integration is 82 (by the Sanquianga) and the minimum market integration is 0 (by the Hadza). Therefore, the range for market integration is 82 − 0 = 82.

To determine the range for participation in world religions, examine the table sort for Mean WR. The maximum participation in world religions is 100 (by several populations) and the minimum participation in world religions is 0 (by the Hadza). Therefore, the range for participation in world religions is

100 − 0 = 100.

The range for market integration is less than the range for participation in world religions.

The correct answer is Yes.

Apt0810 · Answer

1)Yes,The population which forage are :

Au-1->MI rating
Hadza-0
Tsimane-7
Yasawa-21

So they all have lowest MI ratings,since the highest goes upto 72

2)Yes,Since Gusi,Isanga village,and Maragoli depend on farming and wage work and there CS rankings are:Gusi-1,Isanga village-5, Maragoli-2

3)Yes,Range for MI-72-0=72
Range for world religion=100-0=100

1. The populations that forage have the lowest market integration ratings.

The populations that forage are: Au, Hadza, Tsimane, Yasawa. The MI for them are: 1, 0, 7, 21 respectively.

Yes, since these are the populations that have the lowest MI ratings, as it can be seen increasing further.

Answer Yes.

2. Each of the populations that depend on both farming and wage work is sedentary and has a mean community size among the five largest.

Populations that depend on farming & wage work are: Gusii, Isanga Village, Maragoli. It can be inferred from the table that all these populations are  sedentary .
The mean CS of all of the above mentioned populations are: 4063,1500, 3843.

The populations having a mean community size among the five largest are: Gusii, Maragoli, Samburu, Sanquianga & Isanga Village.
Thus, Each of the populations that depend on both farming and wage work is sedentary and has a mean community size among the five largest.

Answer Yes.

3. The range for market integration is less than the range for participation in world religions.
The range for MI= Highest - Lowest => 72 - 0 = 72.
The range for WR = Highest - Lowest => 100- 0 = 100.
So Yes, the range for market integration is less than the range for participation in world religions.

Answer Yes.

mSKR · Answer

1. look for lower MI that has economic base has foraging 
you can find 0 in hadza

YES

2. sedentary : yes in gusii+ maragoli + isnana village 
mean community size= means CS= ( only 5 in 4 digit numbers)

YES

3. MI range= 0 to 82
WR range = 0 to 100

YES

mpobisetty · Answer

For the question: The range for market integration is less than the range for participation in world religions.

We only know  Mean  MI and  Mean  WR. Obviously Mean gives no indication of the individual data-points. Hence, I don't believe we can have any idea about  range .

So, how can we conclude that the range for market integration is less than the range for participation in world religions.

KarishmaB  and  chetan2u , please help.

chetan2u · Answer

If you look at the definition for these terms in the para of the question:-

percentage of population participating in world religions  is ( mean  WR)

So, it is not mean or average in literal sense, it is the % of population doing a certain thing, and thus it will just be a numeric value giving a certain %.

Thus, we have % for each set of people and you have to find the range of this.

nbharti · Answer

degree of market integration (mean MI)—defined as the percentage of calories obtained in the marketplace.

How can the percentage of Calories obtained in the marketplace and the percentage of the population be compared like apples to apples?

chetan2u · Answer

You are not comparing calories with population, you are comparing a statistical data related to them.
You dont require to compare apples with apples when you are comparing costs. It could easily be cost of apples vs cost of oranges.

Here too, you are just comparing the difference in the extreme values of two.

egmat · Answer

Hi nbharti,

Great instinct to question units, but here the two percentages never actually get mixed together, so there's no apples-to-oranges problem.

Notice what statement 3 actually asks:  is the range of Mean MI smaller than the range of Mean WR?  It is  not  claiming a calorie equals a person, or comparing MI directly against WR. It's comparing two  spreads  - and a spread is just a single number you compute  inside one column .

Here's the clean way to see it:

-  Mean MI range  lives entirely in the MI column: max  82  (Sanquianga) - min  0  (Hadza) =  82 .
-  Mean WR range  lives entirely in the WR column: max  100  - min  0  (Hadza) =  100 .

Each range is born from its own column, in its own units. Once you have the two finished numbers,  82  and  100 , you're just asking "is 82 less than 100?" - and that's pure arithmetic. No unit ever crosses over.

It also helps that both columns happen to be percentages on a  0-100  scale, so even the raw magnitudes are naturally comparable. But the key point stands even if they weren't.

A quick parallel to lock it in:  suppose one column is  exam scores  (range  40 ) and another is  students' ages  (range  12 ). Scores and ages are totally different things - yet it's perfectly valid to say "the scores are  more spread out  than the ages," because you're comparing two spread numbers,  40  vs  12 , not equating a score with an age.

Therefore , the comparison is legitimate, and the answer to statement 3 is  Yes .
