Refer to the technology output given to the right that results from measured hemoglobin levels (g/dL.) in 100 randomly selected adult females. The confidence level of 95% was used. a. Express the confidence interval in the format that uses the Tess than" symbol. Assume that the original listed data use two decimal places, and round the confidence interval limits accordingly. b. Identify the best point estimate of u and the margin of error c. In constructing the confidence interval estimate of p, why is it not necessary to confirm that the sample data appear to be from a population with a normal distribution? a. Express the confidence interval in the format that uses the "less than" symbol. Assume that the original listed data use two decimal places, and round the confidence interval limits accordingly.
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.
