Answer:
(A) The mean will decrease more than the median.
Step-by-step explanation:
$500 is much more than the mean of $93.80, so removing it from the data set will decrease the mean significantly. The median of $75.80 will move to the next smaller number, so the change will be small or even none.

Answer:
The value of P( A and B ) is 0.08.
Step-by-step explanation:
When two events are independent then the probability of both occurring is equal to the product of probabilities of both events individually,
That is, If X and Y are independent events,
Then, P(X∩Y) = P(X) × P(Y),
or P(X and Y) = P(X) × P(Y),
Here, P(A) = 0.40 and P(B) = 0.20,
Hence, P(A∩B) = P(A) × P(B)
= 0.40 × 0.20
= 0.08
The answer got to be D. 1/5. Because 1/5=the same thing as 5.
Hope that helps!!
