The constructed interval for the rating of the ice cream mango and cotton candy is; C: (-1.4, 2.6).
<h3>What is the t-interval?</h3>
When the sample size is small and the population standard deviation is unknown, then we will have to say that is when the t-interval is very useful.
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).
