12. | Basic Computation: Setting Hypotheses Suppose you want to test the claim that a population mean equals 30. (a) State the null hypothesis. (b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 30. (c) State the alternate hypothesis if you believe (based on experience or past studies) that the population mean may be greater than 30. (d) State the alternate hypothesis if you believe (based on experience or past studies) that the population mean may not be as large as 30.

Please answer number 12. All parts! Make sure to show work! Thanks!
Transcribed Image Text:7. Statistical Literacy If the P-value in a statistical test is greater than the level
of significance for the test, do we reject or fail to reject Ho?
8. Statistical Literacy If the P-value in a statistical test is less than or equal to
the level of significance for the test, do we reject or fail to reject H₂?
9. Statistical Literacy Suppose the P-value in a right-tailed test is 0.0092.
Based on the same population, sample, and null hypothesis, what is the
P-value for a corresponding two-tailed test?
10. | Statistical Literacy Suppose the P-value in a two-tailed test is 0.0134.
Based on the same population, sample, and null hypothesis, and assuming
the test statistic z is negative, what is the P-value for a corresponding left-
tailed test?
11. Basic Computation: Setting Hypotheses Suppose you want to test the
claim that a population mean equals 40.
(a) State the null hypothesis.
(b) State the alternate hypothesis if you have no information regarding how
the population mean might differ from 40.
(c) State the alternate hypothesis if you believe (based on experience or past
studies) that the population mean may exceed 40.
(d) State the alternate hypothesis if you believe (based on experience or past
studies) that the population mean may be less than 40.
