In one month, the national mean price per gallon (in dollars) of gasoline was 3. 102. The 3.05 3.07 3.07 3.11 data table here represents a random sample of 3.14 3.13 3.13 3.18 20 gas stations in city A. Is gas in city A more expensive than the nation? Assume the data 3. 16 3. 16 3.16 3.18 come from a normal population with no 3.21 3.22 3.19 3.21 outliers. Complete parts (a) through (d) below. 3.24 3.22 3.22 3.26 (a) What type of test should be used? O A hypothesis test regarding the difference between two population proportions from independent samples using the standard normal test statistic O A hypothesis test regarding the difference of two means using a matched-pairs design O A hypothesis test regarding a single population mean using Student's approximate t O A hypothesis test regarding two population standard deviations (b) Determine the null and alternative hypotheses. Ho: integers or decimals.) (c) Use technology to calculate the P-value. (Round to three decimal places as needed.)(d) Draw a conclusion based on the hypothesis test. Choose the correct answer below. O A. No meaningful conclusion can be drawn because no level of significance was stated. B. Although no level of significance is stated, the P-value is so small that the null hypothesis can be rejected. There is sufficient evidence to conclude that the gas prices in city A are higher than the national average. O C. Although no level of significance is stated, the P-value is so small that the null hypothesis can be rejected. There is sufficient evidence to conclude that the gas prices in city A are lower than the national average. O D. Although no level of significance is stated, the P-value is large enough that the null hypothesis cannot be rejected. There is insufficient evidence to conclude that the gas prices in city A are higher than the national average
