Answer:
A one-sample t-interval for a population mean
Step-by-step explanation:
As the question is "How many minutes per day, on average, do you spend visiting social media sites?", the answer will be in a numerical form (number of hours, positive integer or real number).
As this is not a proportion, the option "A one-sample t-interval for a population mean" is discarded.
As the study does not defined another variable to compare in pairs, it is not a matched-pairs test. Option "A matched-pairs t -interval for a mean difference" discarded.
There are not two means in the study, so there is no "difference between means" variable. Options "A two-sample z-interval for a difference between proportions" and "A two-sample t-interval for a difference between means".
This should be a one-sample t-interval for a population mean, as there is only one sample, one population mean and the population standard deviation is not known.
The required correct statement 'A one-sample t-interval for a population mean'.
We have to determine, Which of the following is the most appropriate inference procedure for the sociologist to use?
According to the question,
The sociologist wants to estimate the average total number of minutes spent on social media per day in the population.,
A random sample of 50 high school students was selected,
And they were asked, “How many minutes per day, on average, do you spend visiting social media sites.
The answer will be in a numerical form (number of hours, positive integer or real number).
The time spent on social media keeps increasing. it can deduce as at now that trending social media platforms take much of the time spent on social media.
On average, spend 240 minutes per day on social media sites. As New social media handles keep coming,
As the given condition is not a proportion, the option "A one-sample t-interval for a population mean" is discarded.
The study does not defined another variable n difference" discarded.
There are not two means in the study, so there is no "difference between means" variable.
"A two-sample z-interval for a difference between proportions" and "A two-sample t-interval for a difference between means".
This should be a one-sample t-interval for a population mean, as there is only one sample, one population mean and the population standard deviation is not known.
Hence, The required correct statement 'A one-sample t-interval for a population mean'.
