Labor rate variance is the difference between the actual labor rate and the applied overhead rate (standard rate multiplied by the number of actual hours worked). Consider this and respond to the following: • "Our workers are all under labor contracts. Therefore‚ our labor rate variance is bound to be zero." Do you agree or disagree that the labor rate variance will be zero if all workers are under labor contracts? Explain giving reasons. The concept of labor rate variance and its application

Evolution Lab The finches on Darwin and Wallace Islands feed on seeds produced by plants growing on these islands. There are three categories of seeds: soft seeds‚ produced by plants that do well under wet conditions; seeds that are intermediate in hardness‚ produced by plants that do best under moderate precipitation; and hard seeds‚ produced by plants that dominate in drought conditions. Evolution Lab is based on a model for the evolution of quantitative traits–characteristics of an individual

T-bills average return = 39.31% / 6 U. T-bills average return = 6.55% V. b. Using the equation for variance‚ we find the variance for large company stocks over this period was: Variance = 1/5[(–.1469 – .0324)2 + (–.2647 – .0324)2 + (.3723 – .0324)2 + (.2393 – .0324)2 + (–.0716 – .0324)2 + (.0657 – .0324)2] Variance = 0.058136 And the standard deviation for large company stocks over this period was:

this case the four scores for PD‚ UAV‚ IND and MAS. Vi is the variance of the score of this dimensions. The variances for all dimensions can be calculated in excel. 2. What is the difference between mean and variance? Can you explain the example given in the lecture in your own words? The mean is a weighted average of the possible values a certain variable can take. The mean provides the long-run average of a variable. The variance of a variable measures the spread or variability of the distribution
