***I cant get the last problem of question 4... ***prob.first error is among first 5 prescriptions (use 3decimal places). ???????***
In the article Geometric Probability Distribution forModeling of Error Risk During Prescription Dispensing,American Journal of Health-System Pharmacists, Vol. 63, Issue 11,June 1 2006, the authors use the geometric model to analyze howmany prescriptions a pharmacist can process until the pharmacistmakes the first dispensing error, either in labeling (incorrectinformation or instructions) or drug content (omissions; incorrectdrug, quantity, or strength).
Use this Excel file geometricprobabilities to assist you with the geometric probabilitycalculations required to answer the questions below.
Suppose a pharmacist's error rate is 0.08.
Question 1. On average,how many prescriptions would this pharmacist process until he orshe made the first dispensing error?
CORRECT (use 2 decimal places in youranswer)
Question 2. What isthe median number of prescriptions until thepharmacist makes the first dispensing error? Hint: Use the above geometricprobabilities file to find the smallest value of x such that P(X<= x) is larger than 0.50.
CORRECT
Question 3. What is theprobability that the first dispensing error occurs among thefirst 20 prescriptions?
.755 (Use 3 decimal places in youranswer)INCORRECT
Question 4.A newtrainee pharmacist has an error rate of 0.16. Find the expected number of prescriptions untilthe first dispensing error, the median number of prescriptionsuntil the first dispensing error, and the probability that thefirst dispensing error occurs among the first 5 prescriptions.
CORRECT expected number (use 2 decimal placesin your answer)
CORRECT median number
****** PLEASE HELP****** prob. first error isamong first 5 prescriptions (use3 decimal places). ???????
Explanation / Answer
Because these are independent events, you use the same formulaof: e- k/k! Where is the rate of mistakes, and k is how many trialsthere are e-.16 .165/5! Compute and this is your answer! Hope this helps!Related Questions
