13. A health study is conducted to see if there is a relationship between blood pressure and cholesterol levels. Researchers measure patients' cholesterol levels (measured in mg/dL). The patients are also categorized into three groups based on their blood pressure (normal blood pressure, hypertension stage 1, hypertension stage 2). What test is appropriate to see if there is a relationship between the two variables? t-test for independent samples O t-test for paired data chi-squared test for independence chi-squared goodness-of-fit test O ANOVA O correlation test and linear regression 14. A group of randomly selected rats are chosen for an experiment. The researcher first has the rats run through a maze and records the time it takes the rat to reach the end. The time of this first run is recorded. The researcher then has the rats run through the maze ten more times. They also record the time it takes to complete the tenth run. What kind of test would the researcher use to compare the times between the first-time maze runs and the tenth-time maze runs? O t-test for independent samples O t-test for paired data O chi-squared test for independence o chi-squared goodness-of-fit test O ANOVA o correlation test and linear regression
