We conclude that he used a paired two-sample t-test.
Step-by-step explanation:
We know that the student measuring how gasoline prices change records the cost of gas at 10 randomly selected stations in her hometown. One week later, she records the price again at the same 10 stations.
We conclude that he used a paired two-sample t-test.
Because at each gas station, the student measured the price of gas twice.
29.9, 30.0,30.1,30.5,30.7,30.08,31.0,31.0

so the medium is 30.5 and 30.7
(e) it is the last one........
