Listed below is the number of movie tickets sold at the Library Cinema-Complex, in thousands, for the period from 2001 to 2013. Compute a five-year weighted moving average using weights of .1, .1, .2, .3, and .3, respectively. Describe the trend in yield. (Round your answers to 3 decimal places.)

  There is a regular (Click to select)increasedecrease of approximately 0.2 per year.

Solution

to compute 5 year moving average with weights 0.1 0.1 0.2 0.3 0.3

we have to consider the first 5 observations. then find their average with thosw weights. then exclude the first one and include the next and then again compute the average with the weights and so on ultil we reach at the last 5 observations.

in this process the moving averages are
