A two sample ttest for a difference in means will be conducted to investigate mean gasoline prices in two states. From each state, 45 gasoline stations will be selected at random
On the same day, the price of regular gasoline will be recorded for each selected station and the sample mean price for each state will be calculated
Have all conditions for inference been met?
A Ves, all conditions have been met.
No, the data are not collected using a random method
c No, the sample sizes are greater than 10 percent of the population
No, the sample sizes are not large enough to assume the sampling distribution is approximately normal
No, the distributions of the sample data are not approximately normal.
