An electric car enthusiast wants to buy an electric car! He tests two of his favorite brands with an adequate nominal range to see which one is more consistent in terms of mile per charge on a full charge! He tests a sample of 10 cars of brand A and 11 cars of brand B with the following results (mile per charge):

A: 371 369 388 375 359 382 370 365 381 376 (s = 8.618, x_bar = 373.600)

B: 356 349 361 363 370 368 362 359 362 367 365 (s = 5.916, x_bar = 362.000)

Use your statistics knowledge to help him decide which car is more consistent in range within 5% level of significance!

What is the value of test statistics?
