- Consider the following time series data: Using the naïve method (most recent value) as the forecast for the next week, compute thefollowing measures of forecast accuracy:a. Mean absolute errorb. Mean squared errorc. Mean absolute percentage errord. What is the forecast for week 7?From the table below, find Prof. Robot expected value lateness. X= lateness P (Lateness) on time 4/5 1hr late 1/10 2hrs late 1/20 3hrs late 1/20Suppose that ants are exiting a mound according to a Poisson process with a mean rate of 12 ants per minute. If a point in time is selected, what is the probability that more than 3 seconds will elapse from that time before the next ant exits the mound? What is the mean time (in seconds) until the next ant exits? Round your answers to four decimal places, if necessary. P(T > 8) = μ T =
- Consider the following time series data. a. Show the four-quarter and centered moving average values for this time series (to 3 decimals if necessary). b. Compute seasonal indexes and adjusted seasonal indexes for the four quarters (to 3 decimals).In the article “The World's Longest Continued Series of Sea Level Observations” (M. Ekman, Paleogeography, 1988:73–77), the mean annual level of land uplift in Stockholm, Sweden, was estimated to be 4.93 ± 0.23 mm for the years 1774–1884 and to be 3.92 ± 0.19 mm for the years 1885–1984. Estimate the difference in the mean annual uplift between these two time periods, and find the uncertainty in the estimate.A lumber company is making boards that are 2840.0 millimeters tall. If the boards are too long they must be trimmed, and if they are too short they cannot be used. A sample of 39 boards is made, and it is found that they have a mean of 2838.2 millimeters. Assume the standard deviation is known to be 10.0. Is there evidence at the 0.02level that the boards are too short and unusable? Step 1 of 5 : Enter the hypotheses:
- Q4 A sample of 37 wealth-market mutual funds was chosen on February 1, 2016, and the average annual rate of return over the past 30 days was found to be 3.28 percent, and the sample standard deviation was 0.515 percent. A year earlier, a sample of 43 wealth-market funds showed an average rate of return of 4.41 percent, and the sample standard deviation was 0.89 percent. Is it reasonable to conclude (at α=0.01) that wealth-market interest rates declined during 2015?Consider the following time series data: Week Value 18 13 16 11 17 14 Using the naïve method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy. a. Mean Absolute Error b. Mean Squared Error c. Mean Absolute Percentage Error d. What is the forecast for Week 7?Consider a tower that has leaned an inclination of 18o. The tower continues to lean at annual increment A, which is normally distributed with a mean value of 0.1o and a c.o.v of 30%. Assume that the incremental amounts of additional leaning between years are statistically independent. Determine the probability that the final inclination of the tower after 16 years will exceed 20o.
- Suppose that the life expectancy of a certain brand of nondefective light bulbs is normally distributed, with a mean life of 1300 hr and a standard deviation of 50 hr. If 30,000 of these bulbs are produced, how many can be expected to last at least 1300 hr?

This morning the manager notices that there is 7105.5 litres in storage with the next delivery coming only at closing. a) What is the probability that there will be enough petrol to meet the daily demand? (Rounded to 4 decimal places)Answer b) If a year has 365 days, how many days do you expect the demand to be less than 7105.5 litres? (Rounded to the nearest integer)1.
