Now, the z-interval for calculating confidence intervals becomes less reliable when the sample size is less than 30 i.e very small.
Now, since Mango the greater sample mean rating, and since each person rated the flavor on a numerical scale from 1 to 5, then we can say that the correct option is C; (-1.4, 2.6).
