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.

I hope this is helpful.
The greatest common factor shared by 32 and 44 is 4. This is factored out as follows: 4(8 + 11) = 4(8 + 11), which appears strange to me, but that's how most textbooks illustrate the factoring process.
The correct response is:
3 inches rise for every foot in length
Explanation:
To derive the rate of change, we need to compute the difference in height and the difference in distance. The rate of change is expressed as rise/run, or
(change in height)/(change in length).
The respective heights at the specified points are 18 inches and 12 inches, resulting in a change of 18-12 = 6 inches.
The corresponding lengths at those points are 6 feet and 4 feet, yielding a change of 6-4 = 2 feet.
This implies our rate of change is (6 inches)/(2 feet), which simplifies to (3 inches)/(1 foot), indicating a rise of 3 inches for each foot of incline on the driveway.
