For a binomial distribution with n = 12 and p = 0.6 determine which statement is true.
a. nq < 5
b. np > 5
c. cannot use normal distribution
d. all of the above
For the following conditions, determine if it is appropriate to use the normal distribution to approximate a binomial distribution with n = 20 and q = 0.7.
a. mean > 5
b. standard deviation = 2.05

Match the binomial probability P(x < 23) with the correct statement.
a. P(there are at most 23 successes)
b. P(there are at least 23 successes)
c. P(there are more than 23 successes)
d. P(there are at fewer 23 successes)
P(x ≥ 23) is read as:
a. P(there are more than 23 successes)
b. P(there are at most 23 successes)
c. P(there are at least 23 successes)
d. P(there are more than 23 successes)
Ten percent of the population is left-handed. In a class of 100 students, write binomial probability for the statement "there are at most 12 left-handed students in the class."
a. P(x < 12)
b. P(x ≤ 12)
c. P(x = 12)
d. P(x > 12)
Ten percent of the population is left-handed. A class of 100 students is selected. Convert the binomial probability P(x < 12) to a normal probability by using the correct for continuity.
a. P(x = 11.5)
b. P(x ≤ 12.5)
c. P(x < 11.5)
d. P(x ≥ 12.5)
Find the probability that in 200 tosses of a fair six-sided die, a five will be obtained at most 40 times.
The solution answers to multiple choice questions on Normal, Binomial, Geometric and Poison distributions.
Outline for Capital Budgeting Paper
I have a 15 - 20 page literature review to write that captures relevant theories and empirical research leading to a significant research topic, problem, and research question(s).
I need a 2 page outline to help me write a good literature review on "Capital Budgeting and Long-Term Financing"
I have attached the relevant articles that i intend to use for the literature review but feel free to include other sources as you deem necessary.View Full Posting Details
