no, you cannot divide the sum of the means by 2 to get the overall average, as we do not know the proportion/weights of the sedans and the coupes. you could do that if you knew you had equal number of sedans and coupes

16) If the range is 0, then the SD must also be 0 => good as is

piyushdabomb, your dataset:{-7 1 4 7} has range 14 and not 0

if range =0, the highest and the lowest numbers are the same which implies all numbers in between are also the same in an ordered set. so SD has to be 0.

product of 2 consecutive even numbers is always divisible by 8

1) =>x is odd=> (x+1) and (x-1) are even, so divisible by 8

2) n= 4y*(4y+1)*(4y+2)=> even*odd*even, so divisible by 8

hence, D

C is good.

"likely" is the keyword here. Choi just states a likelihood or a possibility/chance. Hart's argument gives actual data on people who have already earned their doctorate. Choi makes no claim on people who have already earned their doctorate. both their claims are hold.

would go with D.

music should stand independent of its source and have internal coherence(meaningful/logical)

D: "unintelligible " would mean meaningless or incomprehensible, so such a music cannot be internally coherent and stand on its own. =>goes against the passage

would go for D

we need the adverb "seemingly" to modify the adjective-"endless". A and B out. E too wordy.
between C and D, D is more concise. each directly refers to the waves, we do not need "each of those"
