1. In grading shrimp into small, medium and large, the Globe Fishery packs the shrimp that weigh more than 2 ounces in each package marked large and the shrimp that weigh less than 0.75 ounces each into packages marked small; the remainder are packed in medium size packages. If a day's catch showed that 15.87 percent of the shrimp were large and 6.68 percent were small, determine the mean and the standard deviation for the shrimp weights. Assume the weights of the shrimp are normally distributed. a. Mean =1.5 and Standard Deviation =0.5 b.Mean =1.0 and Standard Deviation =1.0 c. Mean =1.0 and Standard Deviation =0.25 d. Cannot be determined from the information given
