Consider the hypotheses shown below. Given that x overbar= 40 ,sigma=11 ,n=33, alpha=0.10 , complete parts a and b.
Upper H 0 : mu less than or=38
Upper H 1: mu greater than38
a. What conclusion should be drawn?
b. Determine the p-value for this test.
a. The z-test statistic is .
(Round to two decimal places as needed.)
The critical z-score(s) is(are) .
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
Because the test statistic
does not fall within the critical values,
falls within the critical values,
is greater than the critical value,
is less than the critical value,
▼
do not reject
reject
the null hypothesis.
b. The p-value is .
(Round to three decimal places as needed.)
