This assignment and unit are overall awarded a distinction. This is Assignment C of Unit 11 and will talk about human inheritance and predicting genetic traits. In this assignment I have given examples of Mendles pea plants, explained F1 and F2 generation, and carried out and investigate Dihybrid and monohybrid inheritance in mazes have concluded my findings using chi-squared and conclusions. I have used drosophila flies, cystic fibrosis, hemophilia, blood group in this assignment as examples.

QUESTIONS AND ANSWERS

Assuming that the data are normally distributed, under the simple linear model, the estimated variance has the following sampling distribution: - Chi-squared with n-2 degrees of freedom. The fitted values are defined as? - The regression line with parameters replaced with the estimated regression coefficients. The estimators fo the linear regression model are derived by? - Minimizing the sum of squared differences between the observed and expected values of the response variable. The estim...

σ^2 (sample distribution of the variance estimator) - is chi-squared distribution with n - 2 degrees of freedom (We lose two degrees of freedom because we replaced the two parameters ß0 and ß1 with their estimators to obtain the residuals.) constant variance assumption - which means that the variance (σ^2) of the error terms or deviances is constant for the given population. A violation of this assumption means that the estimates are not as efficient as they could be in estimating the ...

WGU C207 Exam Questions and Answers 100% Pass Mean -Answer-The mean is the usual average, so add and then divide: (13 + 18 + 13 + 14 + 13 + 16 + 14 + 21 + 13) ÷ 9 = 15. Median -Answer-Re write the list in numerical order. Then it is the middle number. 13, 13, 13, 13, 14, 14, 16, 18, 21. So, the median is 14. Mode -Answer-The mode is the number that is repeated more often than any other. The sample mean can be used as an estimate of the population mode. Range -Answer-The largest value in...
