Records indicate that for some airport during fall months an average of one day in 25 is too foggy for landings. What is the probability that in a period of 7 fall days landings are prevented on 2 or more days? Please say what distribution you used and why. also include the parameters

Records indicate that for some airport during fall months an average of one day in 25 is too foggy for landings. What is the probability that in a period of seven fall days landings are prevented on two or more days?
C1: Snow Manufacturing Co. has 6 machines that perform a particular task. Breakdowns occur frequently for this machine. Past records indicate that the number of breakdowns that occur each day is described by the following probability distribution: SK2: 5 marks Number of Probability Breakdowns 0.2 0.3 0.4 More than 3 0.0 Required: 1. What is the expected number of breakdowns in any given day? (2 marks) 2. What is the variance for this distribution? (1 mark) 3. What is the...
How do I do this in Excel? Business has about 20 customers a day with standard deviation of 6 customers. Assume normal distribution. In an attempt to increase the number of customers, manger offers a $2 discount on 10 consecutive weekdays. Reports strategy works since sample mean of customers during the 10 days period jumps to 25. a. What is the probability of getting a sample average of 25 or more even if the manager does not offer the discount?...
(1 point) Afactory's worker productivity is normally distributed. One worker produces an average of 73 units per day with a standard deviation of 23. Another worker produces at an average rate of 68 units per day with a standard deviation of 20. A. What is the probability that in a single day worker 1 will outproduce worker 2? Probability = B. What is the probability that during one week (5 working days), worker 1 will outproduce worker 2? Probability =...
To boost holiday sales, a jewelry store in Bismarck, North Dakota, is advertising the following promotion: “if more than 7 inches of cumulative snow fall on December 24, 25, 26, 27, and 28, you get your money back on all purchases made on December 17.” To analyze this promotion, the stores manager has collected data and determined that snowfall over these five day period in December is normally distributed with the average of 6 inches and a standard deviation of...
9. (25 points) George keeps track of how often he makes it through stop lights on his way to work every morning and how many times he has to stop. Assume that whether or not he makes it through one light is independent of whether or not he makes it through the next light (there are some reasons why they might not be independent, but for this problem, you can assume that they are). According to George's records, he makes...
I know these three questions are some how challenging because this the fourth time I am posting them, the circled answers are wrong, show steps to arrive to correct answers and will definitely rate more points. tion: Assuming k in a constant, deternine the covariance of X and Y 1) -0933 (22) Ass ume that losses from policyholders A, B, and C are i nentially distributed. The expected loss amount for policyholders A, B and IN 20o, 450, and 700,...
This course is actually Quantitative Methods and Analysis In Unit 2, you have learned about three different types of distributions: Normal, binomial, and Poisson. You can take data that you collect and plot it out onto graphs to see a visual representation of the data. By simply looking at data on a graph, you can tell a lot about how related your observed data are and if they fit into a normal distribution. For this submission, you will be given...
Hello, below is a copy of a homework question. Here they ask the question and then explain how to go about solving it. Could anyone please tell me why ( 0.84162 × 10 = 8.416) was times by ten? i cant find any reason in my notes why this was done. Many Thanks --------------------------------------------------------------------------------------------------------- A busy café manager has to decide how many cookies to order in for the Tuesday lunch rush.
