For the problem below, how can you tell that these are suppose to be Sample data instead of Population data? From the look of it, when it says "... all 10 students took to complete an assignment in a statistics class", I suspected that they're saying the mentioned statistics class only has 10 students; therefore, it'd be Population instead of Sample, but I am wrong.
So how can I tell that there are more than 10 students in that statistic class from the given prompt below?
The following data give the times (in minutes) that all 10 students took to complete an assignment in a statistics class.

Homework Answers
Note that in a class there is a rare possibility that only 10 students are there.
the line "the following data gives the time in minutes that all 10 students took to complete an assignment in a statistics class" means that data is provided for all 10 students. There is no mathematical way to show that all 10 students means population or sample, it depends on the understanding of the language of the problem.

1. In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1equals=not attractive; 10equals=extremely attractive). Construct a confidence interval using a 99% confidence level. What do the results tell about the mean attractiveness ratings of the population of all adult females? 6, 8, 1, 10, 7, 5, 8, 9, 7, 10, 3, 9 What is the confidence interval for the population mean muμ?...

2. Suppose that a random sample of 41 state college students is asked to measure the length of their right foot in centimeters. A 90% confidence interval for the mean foot length for students at this university turns out to be (21.709, 25.091). If we now calculated a 95% confidence interval, would the new confidence interval be wider than or narrower than or the same as the original? b.

Suppose you are interested in finding out how happy the students are at UNR. You design a survey that probes aspects of an individual’s emotional life, and using this survey are able to compute an accuracy index score ranging from 0 (completely miserable) to 100 (nauseatingly happy). You know that the standard deviation of the population (sigma) equals 8; however you do not know, and want to know, what the mean of the population (mu) is. Rather than give the...
