Challenge Problems
Push your limits with advanced challenges
You have an adjusted dataset with residuals showing: [0.5, 0.6, -0.3, -0.1, 0.2]. Calculate the Chi-Square statistic and determine if it's within an acceptable range under hypothesis testing.
💡 Hint: Start with the squared residuals and ensure you adjust the sum correctly.
Given two groups: Group A with samples [2, 3, 4] and Group B with [4, 5, 6], perform a t-Test to determine if their mean values are significantly different.
💡 Hint: Pay attention to sample size as it influences the critical values.
