-This means that gallium has risen in price by 26.6% between 94' & 95'.b)The aggregate price index for 1994 using 1993 as the base year;The aggregate price index = 136 x 100 = 118.21c) The Lospeyres index for 1995 using 1993 as the base year;= (13x1000) + (18x800) + (40x300) + (95x75) x100 (10x1000) + (15x800) + (30x300) + (60x75)Stratified sampling involves our population group down into natural grouping on strata. These strata are based upon mutually exclusive characteristics, meaning that the members of the population can belong to only one of the strata.* Even representation which allows for an equal number of units to be selected from each strata.For example, if you have 5 strata form which to select a sample of size 50, then you would take 10 members form each of five strata.* Proportional representation which is based on
Once achieved this level, the selection of the strata members will become a part of the sample is completed by another sampling method. Suppose it decides to survey 10% of its 50 000 members (sample of 5000). 6c) Your prediction are going to be used as the basis for a multi-million dollar media buy, to be funded as a percentage of sales. Questiona) Deseasonalise each of the month's flight activity to calculate the reasonably adjusted figures for this business. Using this allow you to make informed decisions on how the data set is progressing rather then being influenced by observations that may be dramatic although predictable. A=Ý=118 =108 B= XY = 132 = 1. What is the overall trend in the past year and why? Explain your answer fully. This method may be adequate if the judging is done by a reliable expert. The major disadvantage of this method is that clusters may tend to include units or people with common characteristics, rather than representing a cross-section of the population at large.
