An engineer is looking to test the strength of steel bars produced by a conventional
method and then another by an experimental method. The engineer claims that the two
methods should produce the same results. Given the data below, do we have enough
evidence to reject the engineer's claim at a = 0.10?
Experimental method (each data point is three digits):
395 389 421 394 407 411 389 402 422 416 402 408 400 386 411 405 389
Conventional Method:
362 352 380 382 413 384 400 378 419 379 384 388 372 383
O Reject H_0. There is not enough evidence to reject the engineer's claim.
Fail to reject H_0. There is not enough evidence to reject the engineer's claim.
Reject H_0. There is enough evidence to reject the engineer's claim.
Fail to reject H_0. There is enough evidence to reject the engineer's claim.
