Q1) Emergency calls to the 911 system of Durham, North Carolina, for the past 24 weeks are shown inthe following table:WEEK1456789101112CALLS503525404535203035201540WEEK131415161718192021222324CALLS553525555540356075504065a) Compute the exponentially smoothed forecast of calls for each week. Assume an initial forecastof 50 calls in the first week, and use alpha = 0.2. What is the forecast for week 25?b) Reforecast each period using alpha = 0.6.c) Actual calls during week 25 were 85. Calculate tracking signal for each period.3.

A researcher studies water clarity at the same location in a lake on the same dates during the course of a year and repeats the measurements on the same dates 5 years later. The researcher immerses a weighted disk painted black and white and measures the depth (in inches) at which it is no longer visible. The collected data is given in the table below. Complete parts (a) through (c) below Observation 3 4 Date 1/25 3/19 5/30 7/3 9/13 11/7 Initial Depth, X, 57.1 67.5 70.3 41.2 70.9 44.3 Depth Five Years Later, Y, 54.6 67.7 67.4 41.9 66.6 47.6 a) Why is it important to take the measurements on the same date? O A. Those are the same dates that all biologists use to take water clarity samples. O B. Using the same dates maximizes the difference in water clarity. O C. Using the same dates makes it easier to remember to take samples. O D. Using the same dates makes the second sample dependent on the first and reduces variability in water clarity attributable to date. b) Does the evidence…
