Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as p…

2. Many countries have a population growth rate of 3% (or more) per year. At this rate, how many years will it take a population to double? Use the model A = Aoert.

Suppose a certain country's population has constant relative birth and death rates of 97 births per thousand people per year and 47 deaths per thousand people per year respectively. Assume also that approximately 30,000 people emigrate (leave) from the country every year. Which equation best models the population P = P(t) of the country, where t is in years? dP A. dt = 50P + 30000 dP B. at C. D. **** dP at dP 0.05P - 30000 = 0.05P+ 30000 dt = 0.5P 30000 dp E. dt = 0.5P - 30

In modeling the effect of an impurity on crystal growth the following equation is used: G-GL Go-G KLCM (1) where C is the impurity concentration, Gi is a limiting growth rate, Go is the growth rate of the crystal with no impurity present and KL and M are model parameters. The table below shows the values of growth rates G for several impurity concentrations C, for the values of Go = 310-3ml/min and G1 = 1.810-3ml/min. 75 100 125 C(ppm) G(ml/min)x 103 2.5 2.2 2.04 1.95 50 Recall that in the multiple linear regression approach (generalized least squares method), we write the general linear model as y = coxo + C1x1+c2x2+ + CmXm (2) which is equivalent to Ac = y, where X1 1 yi 1. y2 (4) 1 Ут Then we use the following linear algebra operation to find the parameters co, c1, C2, *, Cm: c= [A"A]*[A"y] (5) (a) Using the multiple linear regression approach (generalized least squares method), write the model in the general linear form y = coxo +C1x1+c2x2 +.+ CmXm (6) and then specify the form of…
