Word-process your assignment within this template.Do not create a new file.Problem 1: Using SymbolsWord-process the symbol for population standard deviation (sigma) in the space below:= Standard DeviationUsing SubscriptsWord-process the symbol for population standard deviation with subscript x (sigma subscript x) in thespace below:(x)Using EquationsWord-process the following five equations:Using Drawing Tool to Create DiagramsSuppose in a large department store, the average number of shoppers is 448, with a standard deviation of21 shoppers. We are interested in the probability that a random sample of 49 different shoppers will yielda sample mean between 441 and 446 shoppers. Create and attach a normal curve to this document withthe following elements: the normal curve, a label of the average number of shoppers, and labels for thesample means of 441 and 446 shoppers. Include all the appropriate symbols.Problem 2: Descriptive StatisticsThe monthly average low temperatures* during different months of year at Manchester, NH are givenbelow:JanuaryFebruaryMarchAprilMayJune5818294050JulyAugustSeptemberOctoberNovemberDecember555344322412Source: www.weather.comWord-process your solutions and answers below.
