Answer:
A one-sample t-interval for estimating a population mean
Step-by-step explanation:
Given the inquiry "On average, how many minutes each day do you spend on social media sites?", the response will be numeric (in hours, whole numbers, or decimals).
This is not a proportion, so the suggestion of "A one-sample t-interval for a population mean" is not applicable.
The study does not specify another metric for paired comparisons, making a matched-pairs test irrelevant. Hence, the option "A matched-pairs t-interval for a mean difference" is also excluded.
Since there are no two means being examined, the options for "difference between means" are not applicable either. Therefore, options like "A two-sample z-interval for a difference between proportions" and "A two-sample t-interval for a difference between means" are dismissed.
The correct approach should be a one-sample t-interval for a population mean, as there is only a single sample and a defined population mean, with the population standard deviation remaining unknown.
