In order to test their hypothesis, they collect the data in the table below. Assume that credit scores are approximatel normally distributed and that the variance in scores is the same between the two groups. What is the p-value for the test? Round your answer to three decimal places. Android Users Credit Scores 507 565 iPhone Users Credit Scores 544 617 675 452 552 673 623 691 631 659 549 681 632 596 695 673 688 653 535 593 749
