Question

Ste?1 (a) Find an interval containing the ponding P-value for a two-tailed test. we are given a Student's t distribution with df. # 9 and t-, 1.890. We wish to find an interval containing the corresponding P-value for a two-tailed test. To do this, we will use the Critical values for Student'st Distribution. Below is an excerpt from this table. one-tail area 0.250 0.125 0.100 0.075 0.050 0.025 0.010 0.005 0.0005 two-tail areal o.500 ?.250 o.200 0.150 0.100 0.050 0.020 0.010 0.0010 d.f.c 0.500 0.750 0.800 0.850 0.900 0.950 0.980 0.990 0.999 0.703 1.230 1.383 1.574 1.833 2.262 2.821 3.250 4.781 0.700 1.221 1.372 1.559 1.812 2.228 2.764 3.169 4.587 0.697 1.214 1.363 1.548 1.796 2.201 2.718 3.106 4.437 10 To determine where the given t-value would fall, we look for the row with heading d.f. - In this row, the sample statistic t = 1.890 falls between t 1.833 and t =

Answer 1

1) degrees of freedom df = 9

2) Sample Statistic t = 1.890 falls between t = 1.833 and t = 2.262
