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.

![Construct a 90% confidence interval of the mean pulse rate for adult females.
\[ \_\_\_ \, \text{bpm} < \mu < \_\_\_ \, \text{bpm} \]
*(Round to one decimal place as needed.)*
Construct a 90% confidence interval of the mean pulse rate for adult males.
\[ \_\_\_ \, \text{bpm} < \mu < \_\_\_ \, \text{bpm} \]
*(Round to one decimal place as needed.)*
Compare the results.
- **A.** The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
- **B.** The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males.
- **C.** The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
- **D.** The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F48e6a7d0-38a2-4f0f-929f-c6198e406298%2Fa2fbc010-03ea-44ba-b58d-bff03f7a71f9%2Fp12rv0a_processed.jpeg&w=3840&q=75)
