Explanation Calculation: In the data set, the first column represents the independent variable and the second column represent the dependent variable. Here the data set B is used. The independent variable is midterm exam score and the dependent variable is final exam score. Of the semester 2011 of Statistic. The answer will vary. One possible answer is given below: Regression: Suppose x 1 ... x n be n sample values of independent variable and the corresponding dependent variable values are y 1 ... y n . The slope and the intercept of ordinary least square can be defined as b 0 = y ¯ − b 1 x ¯ and b 1 = S S x y S S x x . Where, S S x x , S S y y , S x y are the sum of squares due to x, y and xy respectively. x ¯ and y ¯ are the sample mean of the independent and dependent variable respectively. From the regression the fitted line is denoted as, y ^ = b 0 + b 1 x . Residual: A residualis the difference between an observed response and the corresponding prediction made by the least squares regression line (residual = observed – predicted). The i th residual is denoted by e i = y i − y ^ i where, y i is the i th observation and y ^ i is the fitted value from the model

Correlation

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…

High Cholesterol: A group of eight individuals with high cholesterol levels were given a new drug that was designed to lower cholesterol levels. Cholesterol levels, in milligrams per deciliter, were measured before and after treatment for each individual, with the following results: Individual Before 1 2 3 4 5 6 7 8 237 282 278 297 243 228 298 269 After 200 208 178 212 174 201 189 185 Part: 0/2 Part 1 of 2 (a) Construct a 99.9% confidence interval for the mean reduction in cholesterol level. Let a represent the cholesterol level before treatment minus the cholesterol level after. Use tables to find the critical value and round the answers to at least one decimal place.

I worked out the answers for most of this, and provided the answers in the tables that follow. But for the total cost table, I need help working out the values for 10%, 11%, and 12%. A pharmaceutical company produces the drug NasaMist from four chemicals. Today, the company must produce 1000 pounds of the drug. The three active ingredients in NasaMist are A, B, and C. By weight, at least 8% of NasaMist must consist of A, at least 4% of B, and at least 2% of C. The cost per pound of each chemical and the amount of each active ingredient in one pound of each chemical are given in the data at the bottom. It is necessary that at least 100 pounds of chemical 2 and at least 450 pounds of chemical 3 be used. a. Determine the cheapest way of producing today’s batch of NasaMist. If needed, round your answers to one decimal digit. Production plan Weight (lbs) Chemical 1 257.1 Chemical 2 100 Chemical 3 450 Chemical 4 192.9 b. Use SolverTable to see how much the percentage of…
