Challenge: Fourth T-Test

Opgave

Swipe to start coding

Your task is to do a t-test. Recall that the distribution in the 'Earning' column has a normal distribution in both datasets. Also, there is no statistically significant difference between the variances. Are the means of the two samples equal?

  1. Calculate the mean values.
  2. Perform a t-test.
