Suppose that we are testing H0: µ1 = µ2 versus H0: µ1 ≠ µ2 where the two sample sizes are n1 = n2 = 12. Both sample variances are unknown but assumed equal. Find bounds on the P-value for the following observed values of the test statistic. a. t0 = 2.30
b. t0 = 3.41
c. t0 = 1.95
d. t0 = - 2.45

Which expression is equivalent to 4 square root 6 divided by 3 root 2

20 da is equal to a. 2,000 cm. b. 2 m. c. 20,000 cm. d. 20,000 mm

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.
