A random sample of18observations taken from a population that is normally distributed produced a sample mean of42.4and a standard deviation of8. Find the range for thep-value and the critical and observed values oftfor each of the following tests of hypotheses using,=0.01.

Use thetdistribution table to find a range for thep-value.

Round your answers for the values oftto three decimal places.

a.H0:=46

versusH1:<46.

Enter your answer; the range for the p-value for the item a) of the question statement, lower bound

<p-value <

Enter your answer; the range for the p-value for the item a) of the question statement, upper bound

tcritical=

Enter your answer; t_critical

tobserved=

Enter your answer; t_observed

b.H0:=46

versusH1:46.

Enter your answer; the range for the p-value for the item b) of the question statement, lower bound

<p-value <

Enter your answer; the range for the p-value for the item b) of the question statement, upper bound

tcritical left=

Enter your answer; t_critical left

tcritical right=

Enter your answer; t_critical right

tobserved=

Enter your answer; t_observed
