Answer:
21
Step-by-step explanation:
It would be D (2, 3.5). Partitions in the ratio 1:1 means it cuts it in half basically.
I'll leave the computation via R to you. The are distributed uniformly on the intervals , so that
each with mean/expectation
and variance
We have
so that
Now,
and
We have
because and are independent when , and so
giving a variance of
and so the standard deviation is
# # #
A faster way, assuming you know the variance of a linear combination of independent random variables, is to compute
and since the are independent, each covariance is 0. Then
and take the square root to get the standard deviation.
The correct option that matches the graph is option A.
Graph is a fine representation of a network and it describes the relationship between lines and points. The length of the lines and position of the points don't count. Each object in a graph is called a knot.
The four introductory graphs used in statistics include bar, line, histogram and pie maps. The description of a graph is a illustration showing the connections between two or further effects. An illustration of graph is a pie map. noun. A wind or line showing a fine function or equation, generally drawn in a Cartesian match system.
Since it is upside down, it is the one with the negative sign in front of the x. The numbers will continue to increase in the negatives.
Hence, the equation on option A matches the graph.

The given scenario falls under the category of conditional probability. There are a total of 56 people in the fishing group described above. The probability that the a person caught a fish and fished from a boat is 24/56. The probability that he fished from a boat is (24+11)/56. For the conditional probability in this item is,
P = (24/56) / ((24+11)/56) = 24/35 = 0.69
