QuestionDecide which hypdethesis test is appropriale to use. Food researchers wanted to Investigate whe ther the acidity level of medium roasted coffee depends on the origin of coffee for 4 regions: Costa Rica, Columbia, Ethiopia, and Brazil. Hypothesis testing for one population proportion Hypothesis testing for one population mean Hypothesis testing comparing two population proportions Hypothesis testing comparing two population means - independent samples Hypothesis testing comparing two population means - matched pair samples ANOVA Chi-square test of independence T-test for linear relationship

Studdy Solution

STEP 1

1. The researchers are interested in comparing the acidity levels of coffee from four different regions.
2. The data involves more than two groups (regions), suggesting a comparison across multiple groups.
3. The goal is to determine if there is a dependency of acidity level on the origin.

STEP 2

1. Identify the type of data and the number of groups involved.
2. Determine the appropriate hypothesis test based on the data type and research question.

STEP 3

Identify the type of data and the number of groups involved:
- The data involves acidity levels, which are continuous numerical data. - There are four groups (regions): Costa Rica, Columbia, Ethiopia, and Brazil.

STEP 4

Determine the appropriate hypothesis test:
- Since the data is continuous and involves more than two groups, we need a test that can compare means across multiple groups. - ANOVA (Analysis of Variance) is suitable for comparing means across more than two independent groups.
The appropriate hypothesis test to use is:
ANOVA \text{ANOVA}
