How can I find a p-value when given a test statistic only with no df? I am preferably looking for a method with a TI-84 but will accept any answer, here is the question I am trying to answer:
Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). The test statistic in a left-tailed test is z = -2.05.
a- 0.0202; reject the null hypothesis
B-0.0453 fail to reject the null hypothesis
C-0.4798; fail to reject the null hypothesis
D= 0.0404; reject the null hypothesis
THANKS!

Solution :
P-value = P(z < -2.05) = 0.0202
P-value < 0.05
a- 0.0202; reject the null hypothesis

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...

Use the given information to find the p-value. Use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). a. The test statistic in a right-tailed test is z = 1.00. b. The test statistic in a test with alternative hypothesis p 6= 5/7 is z = 2.05. c. The test statistic in a test with alternative hypothesis p < 2/3 in z = −0.45.
