A random sample of 12 observations taken from a population that is normally distributed produced a sample mean of 424 and a standard deviation of 8. Find the range for the p-value and the critical and observed values of t for each of the following tests of hypotheses using, a-0.01 Use the t distribution table to find a range for the p-value. Round your answers for the values of t to three decimal places. a.. Ho: 46 versus H1:

Explanation / Answer

a)

-0.0737 < p value < 0.0737

t critical = -2.718

t observed = -1.559

b)

-0.1473 < p value < 0.1473

t critical left = -3.106

t crtical right = 3.106

t observed = -1.559
