A bank wants to determine whether a customer's current balance can be used to predict future earning potential. What would be the most appropriate procedure to use to analyze data to answer this question? Only choose a test that handles multiple comparisons if such a test is needed. O Chi-square test of association O ANOVA (Analysis of Variance) O Regression Test of Slope or Correlation O Test for a Difference of Proportions O Test for a Difference of Means
Suppose you have two samples with the following values: Sample 1: 2, 8, 6, 5, 4, 7, 5, 9, 6 Sample 2: 3, 5, 4, 8, 7, 5, 5, 7,6 For Sample 1, what are the values for: Mean Median Mode Standard Deviation Variance

Analysis of Variance Use the graph attached below. In this assignment we are interpreting statistics. Questions for each graph: 1.) ANOVA: Is the overall test significant? 2.)Multiple Comparisons: To know which group are different from another, we need to examine the results from the post hoc test analysis? 3.)Discriptives: Discuss final results using APA format. In addition to referring to information from the previous two tables, you will need to incorporate information from the third table
6. Explain the reasoning behind announcing one's choice of using a one-tailed test before performing the statistical analysis on an observed data set.
Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?
