Use the following to answer the questions below:

As of July 8, 2020, the national average price for a gallon of regular unleaded gasoline was $2.18. The prices for a sample of n = 10 gas stations in the state of Illinois are provided. $2.365 $2.417$2.437 $2.421$2.396 $2.444$2.422 $2.374$2.422 \$2.447
It is of interest to use this sample to compare the average gas price in Illinois to the national average.

Define the appropriate parameter(s) and state the hypotheses for testing if this sample provides evidence that the average gas price in Illinois exceeds the national average.

▸ Parameter: μ  = average gas price in Illinois
Hypotheses: H0 : μ = 2.18 versus Ha : μ ≠ 2.18

▸ Parameter: μ  = average gas price in Illinois
Hypotheses: H0 : μ = 2.18 versus Ha : μ > 2.18

▸ Parameter: μ  = average gas price in Illinois
Hypotheses: H0 : μ > 2.18 versus Ha : μ = 2.18

▸ Parameter: μ  = average gas price in Illinois
Hypotheses: H0 : μ ≠ 2.18 versus Ha : μ = 2.18
