Question 2

When calculating the degrees of freedom for a hypothesis test comparing two population means with population variances that are unknown and assumed to be unequal, always round up the degrees of freedom to the next highest integer.
 
  This makes it more challenging to reject the null hypothesis which is a more conservative approach. Indicate whether the statement is true or false
