Dynamic random-access memory (DRAM) memory chips are made from silicon wafers in manufacturing facilities through a very complex process called wafer fabs. The wafers are routed through the fab machines in an order that is referred to as a recipe.
 
  The wafers may go through the same machine several times as the chip is created. The data file DRAM Chips contains a sample of processing times, measured in fractions of hours, at a particular machine center for one chip recipe.Compute the mean processing time.A) 0.24 minutes
  B) 0.22 minutes
  C) 0.31 minutes
  D) 0.33 minutes

Answer to Question 2

Descriptive statistics includes methods for summarizing a data set. The two major types of descriptive statistics are (1 ) charts and graphs, and (2 ) summary numerical measures. Charts and graphs include picture type tools such as histograms, bar charts and pie charts that visually summarize a data set. Numerical summary measures are numbers such as the average that describe a characteristic of the data set.
