The following table shows the least expensive gas prices for three cities on June 1, 2018, as reported by Gasbuddy.com.

a. Assuming the overall level of significance is 0.05, what is the Bonferroni-correct level of significance for the three pairs of cities?

b. Report the sample mean for each city. Which two means are closest to each other?

c. Carry out two-sample t-tests for all three pairs. Instead of using the four-step method, summarize your findings using a table that reports t-test statistics, p-values, and conclusions. Base your conclusions on the Bonferroni-corrected level of significance. Do not assume equal variances. Assume all conditions for two-sample t-tests are met.
