Low Lead Level: n = 78, x= 92.88462, s = 15.34451 High Lead Level: n = 33, x = 86.90476, s = 8.988352 1: Find the value of the test statistic and p-value following the instructions below: a) Press STAT & scroll to TESTS & select "2-SampTTest..." (option 4 in T183Plus) & pressEnter (for a hypothesis test of a claim involving two populations b) Enter the following: . Inpt: Stats (The statistics are given above) . x1 = sample mean from the low lead level group . Sx1 = sample standard deviation from the low lead level group . n1 = sample size from the low lead level group . X2= sample mean from the high lead level group . Sx2 = sample standard deviation from the high lead level group . n2 = sample size from the high lead level group . Choose the correct direction of the alternative . Pooled: Choose NO c) Highlight "Calculate" and press ENTER & make note of the calculations as you will need them below. Enter the value of the P-Value. Round to three decimal places if necessary. P-value =
