You began with assessing internal controls over purchasing, specifically purchase transactions. Based on experience you decided on an 8% tolerable deviation rate. Given the importance you believed a 95% confidence level is justified. After estimating the expected deviation rate (4%) you selected a sample size of 100. Sixty sample items had values greater than $5,000 and was selected first. The remaining sample was selected at random from the month of January. January was chosen because most of the purchases were made in January. The sample was taken and eight deviations were found. The attribute tested was purchase authorization. Therefore, you chose vendor invoices as your sampling unit. You discovered following deviations were found. One invoice was not found One invoice was voided Three invoice was missing supporting documentation One invoice amount did not match the supporting documentation Two sampling units were credit memos not invoices Your conclusion is that the internal controls over purchasing is weak and additional accounts payable substantive testing is required. Required: List any weaknesses or improper assumptions used in the sampling.

Probability that stock A ends the day with a price below K20 is 40%. The probability stock B ends the day with a price below K20 is 25%. The probability stock A ends the day with a price below K20 given stock B ends the day with a price below K20 is 60%. Calculate the probability stock A or stock B ends the day with a price below K20.

1. A probability experiment is conducted. Which of the following cannot be considered a probability of an outcome? 1) 0.23 2) 1.00 3) - 0.34 4) 0.05

b- In a scientific study there are eight guinea pigs, five of which are pregnant. If three are selected at random without replacement, find the probability that all three are pregnant. P(all three are pregnant) =

How probability and statistics are related?

Explain the role of probability in statistics according to the following rules:

Your posts must be written according to the following criteria:

• Must demonstrate your understanding of the topic.
• Connections between videos content and textbook content should be exhibited.
• Relate new information with personal experience.
• Discuss at a critical level – don’t just recite facts from your readings or discussion. Critical discussion includes your opinion of items mentioned, but also includes the reasons you hold that opinion, and why it may be inconsistent or consistent with what you’ve learned. Justify your reasoning with facts. How does what you’re presenting affect present and future situations?

• Suppose the probability of a part being manufactured by Machine A is 0.6

• Suppose the probability that a part was manufactured by Machine A and the part is defective is 0.09

• Suppose the probability that a part was NOT manufactured by Machine A and the part IS defective is 0.13

Find the probability that Machine A produced a specific part, given that the part was defective. Round your final answer to 2 decimals, if needed.

We will roll a die (half of a pair of dice) and if it comes up with one or two spots showing, you win and I will pay you $1.50. If it comes up with three, four, five, or six spots showing, you lose and you will pay me $1.00. So, the probability that you will win is 1/3 and the probability you will lose is 2/3. What is the expected value of this game for you?

True or False:

13. A classical probability measure is a probability assessment that is based on relative frequency.

14. The probability of an event is the product of the probabilities of the sample space outcomes that correspond to the event.

15. If events A and B are independent, then P(A|B) is always equal to P(A).

16. Events that have no sample space outcomes in common and, therefore cannot occur simultaneously are referred to as mutually independent events.
17. The binomial experiment consists of n independent, identical trials, each of which results in either success or failure and the probability of success changes from trial to trial.
18. The standard deviation of a binomial distribution is np(1-p).

19. In a binomial distribution the random variable X is discrete.

20. The standard deviation and mean are the same for the standard normal distribution.

21. In a statistical study, the random variable X = 1, if the house is colonial and X = 0 if the house is not colonial, then it can be stated that the random variable is continuous.

22. For a continuous distribution, P(X ≤ 10) is the same as P(X<10).

23. For a continuous distribution, the exact probability of any particular value is always zero.

24. For a binomial probability experiment, with n = 60 and p =.2, it is appropriate to use the normal approximation to the binomial distribution without continuity correction.

25. All continuous random variables are normally distributed.
