Question 3 Data collected on patient days in a hospital over the past 12 months are shown in the following table. Month Patient Days January 543 February 528 March 531 April 542 May 558 June 545 July 543 August 550 September 546 October 540 November 535 December 529 a) Using a weight of .50 for the most recent observation, .30 for the second most recent, and .20 for third most recent, compute a three-month weighted moving average for the time series. Compute the MAD, MSE and MPE for this method.( b) Use exponential smoothing with a smoothing constant of 0.30 to forecast the patient days. Assume that last period's forecast for month 1 is equal to actual to begin the procedure. Which method do you think is best? Is this an improvement over the weighted average- use MAD only c) Use regression analysis to estimate the line of best fit -use the manual method with the formulas shown below.(

Subject: Qualitative research method Q#1: Identify the sampling techniques, sampling frame, and sample size in the following scenarios. a) Consider a scenario where an organization is looking to survey the performance of Internet connectivity across Pakistan. They can divide the entire country’s population into cities and select further towns with the availability of the internet. b) The working approach of top managers in an organization is quite different from that of middle managers. If there are 60% top managers and 40% middle managers in this organization, and if a total of 30 people is to be interviewed to find the answer to the research question, then 18 top managers and 12 middle managers will be chosen for the collection of data through an interview, because these numbers represent 60% and 40% of the sample size.
