   Question

   Suppose a teacher wants to test whether the average number of days that students spend a week on statistics is higher than 3 days.
   Which type of test would he best use?

   
   
   1. TRUE: One-sample t-test
   2. FALSE: Independent t-test
   3. FALSE: Chi-square test
   4. FALSE: Simple regression
   
   

   Solution

   It is a one sample t test, because The One Sample t Test** is commonly used to test the following:**

   1. Statistical difference between a sample mean and a known or hypothesized value of the mean in the population.
   2. Statistical difference between the sample mean and the sample midpoint of the test variable.

   The independent t-test, is an inferential statistical test that determines whether there is a statistically significant difference between the means in two unrelated groups.

    Use the chi-square test for independence to determine whether there is a significant relationship between two categorical variables.

   Use a simple regression to describe the relationships between an independent variable and a dependent variable.
