El Dorado Industries sells perishable farm products to retailers throughout its market area. Recently, losses due to spoilage have reached unacceptable levels and the Quality Control Division has been asked to explain what factors might be associated with these losses.

Data for n = 150 observations collected on the variables seen here produce this partial printout. You are asked to fill in the missing values that somehow were not reported. You can use either t-values or Zvalues given the large sample size. Excel functions of TDIST and TINV will provide much of the missing information.
