Definitions . 3.1. Fecal coliform bacteria are gram-negative, non-spore-forming rods that are found in the intestinesWhat we want to know is the “most probable number (MPN)”, the density which maximizes the probability of obtaining the observed result. Such a density is obtained by finding root of the derivative of log likelihood function. Therefore, the MPN is given by the root of the following equation and calculating MPN per 100 g might have improved the. probability of detection and will be considered for future. peanut crop screening studies.

We know that the marginal revenue product of labor is equal to the wage rate in equilibrium. By calculating the marginal revenue product we can find the nominal wage rate. Marginal revenue product of labor=P*Marginal Product of labor. Here, P=$10 and MPN when they hire 4 labors is=7. So, MRPN=10*7=70=Wage. So, the nominal wage rate is=$70 1,300 x $1.68 = $2,184. 400 * $0.35= $140. Lastly, add up the cost per class code: $2,184 + $140 = $2,324. Based on these 2018 rates in Indiana, this plumbing business with $170,000 in payroll could expect to pay approximately $2,324 in annual workers’ compensation cost - or, less than $200 per month.Open the Geometric Mean Calculator spreadsheet.
