Question

Select True or False from each pull-down menu, depending on whether the corresponding statement is true or false.

? True False **1.**
Conditional probability is the probability that an event will
occur, given that another event could also occur.

? True False **2.**
Marginal probability is the probability that a given event will
occur, with no other events taken into consideration.

? True False **3.**
The outcome of a game of roulette based on historical data is not
an example of the relative frequency approach to probability.

? True False **4.**
Two or more events are said to be independent when the occurrence
of one event has no effect on the probability that the other will
occur.

Answer #1

Conditional probability is the probability that an event will occur, given that another event could also occur. FALSE

2. Marginal probability is the probability that a given event will occur, with no other events taken into consideration FALSE

The outcome of a game of roulette based on historical data is not an example of the relative frequency approach to probability. FALSE

4. Two or more events are said to be independent when the occurrence of one event has no effect on the probability that the other will occur. . TRUE

possible outcomes for a given event.
True False
2. In the normal distribution, the
mean, median, mode, and variance are all at the same position on
the horizontal axis since the distribution is symmetric.

2. The difference between a sample
mean and the corresponding population mean is called a sampling
error.

State, with evidence, whether each of the following
claims is true or false:
a. The conditional probability of A, given B, must be
at least as large as the probability of A.
b. An event must be independent of its complement.
c. The probability of A, given B, must be at least
as large as the probability of the intersection of
A and B.
d. The probability of the intersection of two events
cannot exceed the product of their individual...

1. Indicate if each of the following is true or false. If false,
provide a counterexample.
(a) The mean of a sample is always the same as the median of
it.
(b) The mean of a population is the same as that of a
sample.
(c) If a value appears more than half in a sample, then the mode
is equal to the value.
2. (Union and intersection of sets) Let Ω = {1,2,...,6}. Suppose
each element is equally likely,...

Part I. Indicate whether true or false (T or F).
____ Storm water detention ponds typically are designed to
regulate the outflow peak rate at or below a single target value,
such as the pre-development (pre-land use change) peak runoff rate
for a specified return period event. Detention storage alters the
peak but not the volume of the outflow hydrograph.
_____ Typical rating curves for weirs are concave upward.
Typical rating curves for orifices are concave downward.
____ A sediment...
