Patterns of Nonmarital Childbearing in U.S. MAT 540 Statistical Concepts for Research Ashford University Patterns of Nonmarital Childbearing in U.S. Introduction Trends in nonmarital childbearing in the U.S. have increased steadily since 1970 for non-Hispanic white‚ Black‚ Hispanic‚ and Asian women across all age groups (Wildsmith‚ Steward-Streng‚ and Manlove‚ 2011). Windsmith et al (2011) stated that the rise in the number of children being born outside of marriage among all ethnic and

The objective function of the manager is to minimize the total transportation cost for all shipments. Thus the objective function is the sum of the individual shipping costs from each plant to each waste disposal site: Minimize Z = 12+ 15+ 17+ 14+ 9+ 10+ 13+ 20 +11 +17 +16 +19 +7 +14 +12 +22 +16 +18 The constraints in the model are the number of barrels of wastes available per week at each

days. Intervals between Breakdowns Intervals between breakdowns are a probability distribution. The variables will be random and range between 0 through 6 weeks. As the time continues‚ the probability will increase. To determine this number a function of x will be used‚ as illustrated. F(x) = x/18‚ for 0 thru 6‚ where ’x’ equals the weeks between machine breakdowns F(x) = x2/36‚ for 0 thru 6‚ this is the distribution function that can be further simplified r1 = x2/36‚ to simplify

Let us examine the following condition of complete observations given above. Assume that $\Upsilon_{\chi}$ is taken as distribution function whose total failure times is studied using gamma distribution applied to the shape parameters $3$ together with scale parameters $2.$ On side of repair time it goes with the same way failure time with gamma distribution together with shape parameter $1‚$ and scale parameter $2$ respectively. The time $\tau$ is examined as the following $\tau=2.5‚\tau=5‚$ and
