EEMT 5510 Homework #5 12-24. An improved design of a computerized piece of continuous quality measuring equipment used to control the thickness of rolled sheet products is being developed. It is estimated to sell for $125‚000 more than the current design. Based on present test data‚ however‚ the typical user has the following probabilities of achieving different performance results and cost savings (relative to the current unit) in the first year of operation (assume these annual cost savings

Information Systems Success: The Quest for Dependent Variable By William H. DeLone and Ephraim R. McLean Dependent variables are needed to be well defined in the IS success examination. Prior research more concerns on independent variables than the dependent variable. Instead‚ this article focuses on the measurement of the dependent variable. Shannon and Weaver (1949) and Mason (1978) yield six distinct categories or aspects of information systems success‚ which are system quality‚ information

Estimate the probability that the number of heads lies between 40 and 60 using central limit theorem(the word between in mathematics means inclusive of the endpoints). Solution: The expected number of heads is 100 1 = 50‚ and the variance for the number of heads is 2 11 100 2 2 = 25. Thus‚ since n = 100 is reasonably large
