Test the claim about the difference between two population means 1 and 2 at the level of significance a. Assume the samples are random and independent, and the populations are normally distributed. Claim: 2; a = 0.01 Population parameters: 0 =3.5, 02 = 1.6 Sample statistics: x =16, n =29, x2 = 18, n = 28 Determine the standardized test statistic Z= (Round to two decimal places as needed.) Determine the P-value. P-value= (Round to three decimal places as needed.),
