Concept explainers

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 predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

Brandon works as a statistician for the Toronto Blue Jays, and wants to analyze the relationship between a player's age and how many strikeouts they accumulate in a season. He takes a sample of 5 Blue Jays players with age between 25 and 34 and finds there is a linear relationship between their ages and the number of strikeouts they had in the 2015 season. Here are the numerical summaries for age and the number of strikeouts: r = 0.6, age = 25.3, Sage = 3.2, strikeout = 105.7, S strikeout = 7.48 a) What is the value of b₁, the estimated slope?

The data set Pain contains hypothetical data for a clinical trial of a drug therapy to control pain. The clinical trial investigates whether adverse responses increase with larger drug doses. Subjects receive either a placebo or one of four drug doses (1, 2, 3, or 4 units). An adverse response is recorded as Adverse = 'Yes'; otherwise, it is recorded as Adverse = 'No'. The number of subjects for each drug dose and response combination is contained in the variable Count. (a) Construct a contingency table that corresponds to the data set created above. What type of variable is Dose? (B) Compute the sample proportions of adverse responses at each dose level. Do you observe any trend in the proportion of adverse responses with respect to dose level? (C) Conduct a Cochran-Armitage trend test at the 5% significance level to address the interests of the trial.
The Crazy Nut Company wishes to market two special nut mixes during the holiday season. The Fancy Mix contains 0.5 pound of peanuts and 0.5 pound of cashews. The Deluxe Mix contains 0.6pound of peanuts, 0.2 pound of cashews and 0.15 pound of almonds. Fancy Mix sells for $12 per can and Deluxe Mix sells for $16 per can. The data pertinent to the raw ingredients appear in the table. The Crazy can sell all cans of either mix that it produces, but wants to keep the production quantity of Fancy Mix at least twice as many as Deluxe Mix. Formulate an LP model to determine how many of each mix to produce to maximize the total profit. Do not solve it. You can formulate as a spreadsheet model or an algebraic model. Define your decision variables (changing cells) clearly. Ingredient Amount Available (lb) Cost Per Pound (s) Peanuts 300 $1 Cashews 120 $3 Almonds 90 $4

The U.S. Bureau of the Census predicted that the population of Florida would be about 17.4 million in 2030 and then would increase by about 0.22 million per year until 2030. Which of the following linear models predicts the population, y, of Florida (in millions) in terms of x, the number of years since 2010. O y = 17.4x + 0.22 O y = -0.22x + 17.4 O y = 0.22x + 17.4 Oy = -17.4x + 0.22
