- Flood damage in any year is given according to the following table. With your combined knowledge on probability and engineering economics, what is the present worth of flood damage for a ten year period? use 6% as the effective annual interest rate. Damage Probability 0 0.75 10,000 0.20 20,000 0.04 30,000 0.01The mean average of the numbers a, b, 8, 5, and 10 is 6, and the variance is 6.80. What set of the given numbers a and b that agree to the given mean average value and the variance of the population? i: a=0, b=7 ii: a=5, b=2, iii. a=1, b=6, iv. a=3, b=4 Subject: Applied StatisticsSuppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz): 15.87 16.02 15.78 15.83 15.69 15.81 16.04 15.81 15.92 16.10 On the basis of these data, can you conclude that the mean fill weight is actually less than 16 oz? State the appropriate null and alternate hypotheses. Compute the value of the test statistic. Find the P-value and state your conclusion.

If a random sample of 64 customers is observed, find the probability that their mean time at the teller’s window is: a. at most 2.7 minutes; b. more than 3.5 minutes; c. at least 3.5 minutes but less than 3.4 minutes.3. we heard that there was a 90% confidence interval for the population mean from 22.5 to 28.3, determine A. the point estimate of the population B. the margin of error associated with the informationFrom time to time we check out the time,do you encounter random or systematic error?how to minimize the random or systematic error?
- For Problem 19.39 , determine the probability (assuming normal distribution) that a tire could be used reliably for more than 50,000 kilometers.The next time you make a trip to a supermarket, ask the manager if you can measure the mass of at least 10 cereal boxes of your choice. Choose the same brand and the same size boxes. Tell the manager this is an assignment for a class. Report the average mass, variance, and standard deviation for the cereal boxes. Does the manufacturer’s information noted on the box fall within your measurement?For Problem 19.39 , determine the probability (assuming normal distribution) that a tire could be used reliably for less than 45,000 kilometers.
