here is my work:
c. z interval, a t-interval df 6, b. t interval df 2
Is this correct?
You construct three 88% confidence intervals as follows:
A. A t-interval with 6 degrees of freedom.
B. A t-interval with 2 degrees of freedom.
C. A z-interval
Assuming the mean and standard deviation are the same for all three intervals, write the three intervals (A, B, and C) in order, from narrowest to widest.
