Answer: It is mutually exclusive and exhaustive.
Step-by-step explanation:
Since we have given that
Owns apple No apple Total
With kids 500.2 319.8 820
Without kids 182.4 197.6 380
Total 682.6 517.4 1200
P(Households without kids) = 
P(Households with kids) = 
And P(A∪B) = 0.316+0.683 = 0.999 ≈ 1
Since the two event are disjoint so, the probability of both occurring is 0 and the probability of either occurring is the sum of each occurring.
Hence, it is mutually exclusive and exhaustive.
True, because the standard deviation describes how far, on average, each observation is from the typical value. A larger standard deviation means that observations are more distant from the typical value, and therefore, more dispersed.
