If a hypothesis test were to be performed, in which of the following contexts would a t-test be appropriate? Select the correct answer below: O A sample of 21 dogs is taken from the dogs within a county with approximately normally distributed weights The sample mean is 22 pounds and the sample standard deviation is 3 pounds. The population standard deviation is 2.5 pounds. O A convenience sample of 29 two-inch candles is taken from the candles offered at a candle store and the burning times were collected. The sample is used to estimate the burning times for all the candles in the store. The sample mean is 4 hours and the sample standard deviation is 1.25 hours. O A sample mean of 20 minutes and a sample standard deviation of 4 minutes are obtained using a simple random sample of 11 individuals from the residents of a city, which have approximately normally distributed commute times. O A sample mean of 90 and sample standard deviation of 7 are obtained using a simple random sample of size 25 from a normally distributed population with standard deviation 2.
