A two-sample t-test 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.

Answer:

All conditions have been met

Explanation:

The data are being collected using a random method. The sample sizes are large enough (both 45) to support the assumption of normality for the sampling distribution of the difference in sample means. Also, it is reasonable to assume that 45 gasoline stations is less than 10 percent of all the gas stations in each state.
