For which of the following is a t-test appropriate for performing a hypothesis test? Select the correct answer below: O A convenient sample of 23 individuals is taken from the residents of a city with approximately normally distributed commute times. The sample mean is 19 minutes and the sample standard deviation is 2 minutes. O A population is used to obtain a sample mean of 53 and a sample standard deviation of 7 based on a convenient sample of size 19. O A sample mean of 70 and sample standard deviation of 7 are obtained using a simple random sample of size 19 from a normally distributed population. O A sample mean of 194 pages and a standard deviation of 37 pages are obtained using a simple random sample of 30 books from a public library having approximately normally distributed numbers of pages. The population standard deviation is 31.4 pages.

Select the correct answer below:
O
A convenient sample of 23 individuals is taken from the residents of a city with approximately normally
distributed commute times. The sample mean is 19 minutes and the sample standard deviation is 2 minutes.
O
A population is used to obtain a sample mean of 53 and a sample standard deviation of 7 based on a convenient
sample of size 19.
O
A sample mean of 70 and sample standard deviation of 7 are obtained using a simple random sample of size 19
from a normally distributed population.
O
A sample mean of 194 pages and a standard deviation of 37 pages are obtained using a simple random sample
of 30 books from a public library having approximately normally distributed numbers of pages. The population
standard deviation is 31.4 pages.
