A random sample of 85 group leaders, supervisors, and similar personnel revealed that on the average a person spent 6.5 years on the job before being promoted. The standard deviation of the sample was 1.7 years. Using the 0.95 degree of confidence, what is the confidence interval within which the population mean lies?
Answer(s): E
Interval estimate can be found from x_bar +/-z*s/(n^0.5). Here we have n = 85, x_bar = 6.5 and z = 1.96 (for 95%) and s = 1.7. Therefore 6.5+/-1.96*1.7/9.22 and we get 6.14 and 6.86.
You are examining a group of 20 mutual funds. You find that 10 have a 5% cash position, 4 have a 10% cash position, and 6 have a 2% cash position. What is the weighted average cash position of these 20 mutual funds?
Answer(s): B
A weighted-average is equal to the sum (as i goes from 1 to n) of w_i * X_i, where w_i is the percentage weight of the ith item, and X_i is the value of the ith item. Here, we get a weighted mean of 10/20 * 0.05 + 4/20 * 0.10 + 6/20 * 0.02 = 5.10%.
What is the critical z-value for a one tailed lower test at the 1% level of risk?
This is found by subtracting the 0.01 from 0.5 and then finding the z-value for 0.49.
What is the annual Internal Rate of Return of this series of annual cash flows: Year 0: <$15,000>, Year 1:$2,000, Year 2: $0, Year 3: $15,000, Year 4 to indicate a negative number).

Suppose you are modeling GNP, and you believe that the probability that GNP will expand if interest rates fall is 70%; if interest rates stay constant, you believe that there is a 29% chance of expanding GNP; if interest rates increase, you believe that there is a 1% chance of GNP expanding. You think that the likelihood of interest rates falling is 60%; of staying the same is 30%; of increasing is 10%. What is the unconditional probability of GNP expanding?
Answer(s): C
We use the total probability rule: P(A), the unconditional probability, = P(A|S_1)*P(S_1) + P(A|S_2) *P(S_3) + P (A|S_3) *P(S_3), where the S_i represent mutually exclusive and exhaustive events. So the likelihood of interest rates increasing is 0.70 * 0.60 + 0.29 * 0.30 + 0.01 * 0.10 = 0.42 + 0.087 + 0.001 = 0.508.

just passed the az-500 exam this last friday. most of the questions in this exam dumps are in the exam. i bought the full version and noticed some of the questions which were answered wrong in the free version are all corrected in the full version. this site is good but i wish the had it in an interactive version like a test engine simulator.
i can practice for exam
please i need this exam.
i need the dump
i want it bad, even if cs6 maybe retired, i want to learn cs6
i hate comptia with all my heart with their "choose the best" answer format as an argument could be made on every question. they say "the "comptia way", lmao no this right here boys is the comptia way 100%. take it from someone whos failed this exam twice but can configure an entire complex network that these are the questions that are on the test 100% no questions asked. the pbqs are dead on! nice work
very good materials
thanks for your support.
iam impressed with the quality of these dumps. they questions and answers were easy to understand and the xengine app was very helpful to use.
not bad but you question database from isaca
awesome contents
answer to 134 is casb. while data loss prevention is the goal, in order to implement dlp in cloud applications you need to deploy a casb.
are these brain dumps sufficient enough to go write exam after practicing them? or does one need more material this wont be enough?
i did attend the required cources and i need to be sure that i am ready to take the exam, i would ask you please to share the questions, to be sure that i am fit to proceed with taking the exam.
why only give explanations on some, and not all questions and their respective answers?
refresh db knowledge
interested for sap certification
