A university professor believes that some of his students are struggling in the class due to a large amount of assignments in the course. He runs an analysis of all of the classes in the department to determine if there is a relationship between number of assignments in a semester (1, 2, 3, 4, 5, etc., etc.) and final grades (60, 65, 70, 75, 70, etc., etc.).What type of statistical test should be used?

Chi Square

Independent t-test

Correlation Analysis

 ANOVA

• With 95% confidence, the program director estimated that the proportion of MGMT650 students that are very satisfied is 90% +_ 5%.

  CHOOSE

  1. There is a 5% probability that the true proportion of very satisfied students falls below 85% and 95%.

  2. With 95% probability, the true proportions of very satisfied students falls below 85% and 95%.

  3. The proportion of very satisfied students cannot be off by more than 5%.

  4. With 95% probability, random confidence intervals contain the true proportion. Loosely, we say that with 95% confidence.
