In one month, the national mean price per gallon (in doliars) of gasoline was 3.105. The data table here represents a random sample of 20 gas stations in city A. Is gas in city A more expensive than the nation? Assume the data come from a normal population with no outliers. Complete parts (a) through (d) below (a) What type of test should be used? A hypothesis test regarding the difference between two population proportions from independent samples using the standard normal test statistic A hypothesis test regarding two population standard deviations A hypothesis test regarding a single population mean using Student's approximate t A hypothesis test regarding the difference of two means using a matched-pairs design (b) Determine the nul and altemative typotheses. (c) Use technology to calculate the P-value. (Round to three decimal places as needed.) (d) Draw a conclision based on the bypothesis test. Choose the correct answer below. A. Arthough no levol of significance is stahod, the P. value is so smal that the null hypothesis can be repected. There is sumfient evidence so conctude hat the gas prices in city A are lover than the natenal overage. 0. Amhovgh no level of significance is stated, the Pivalus is so smal thot the mull hypothess can be repected thace is sumtiont evidence fo canclude that the gas prices in eily A are higher. than the natonat average. c. No meaninghi conovelon can be drawn becaise no level of significagce was staled D. Athough no level of slgrificance is saded, the Pryate is large enough that the null hypothesis cannot be rejcted. There is insuiticient tevidence to concude that the gas prices in cilf A are highee than the national average
