What is the probability that a randomly selected employee works
part-time or as a medical employee?
What is the probability that a randomly selected employee works
on a full-time basis given that they are an administrative
employee? report to 3 decimal places.
The following sample was taken:
1, 9, 11, 3, 12, 15, 16, 8, 7, 8, 12, 3, 2, 6, 6, 7, 8, 10, 9, 5,
6, 7, 8, 6, 8, 7
a. Calculate the average
b. Estimate the variance
c. Build a 95% confidence interval for the standard
deviation.
Please, give your answer by hand. Thanks in
advance.
ABC Inc. has provided returns of 6%, 12%, -16%, 4%, 8%, 3%, -5%,
8%, -11%, and 14% over the past ten years. Compute the arithmetic
and geometric means of the returns. What was the standard deviation
of the returns?
a) Compute the indicated quantity.
P(A | B) = .1, P(B) = .4. Find P(A ∩ B).
P(A ∩ B) =
b)Compute the indicated quantity.
P(A) = .1, P(B) = .2. A and B are independent. Find P(A ∩
B).
P(A ∩ B) =
c)Find the conditional probability of the indicated event when
two fair dice (one red and one green) are rolled. HINT [See Example
1.]
The red one is 1, given that the sum is 7.
