Find the P - value for the test statistic ?=2.74z=2.74
for the following null and alternative hypotheses:
?0H0: The population mean is 5.
??Ha: The population mean is less than 5.
The P - value is
(b) Find the P - value for the test statistic ?=2.74z=2.74
for the following null and alternative hypotheses:
?0H0: The population mean is 5.
??Ha: The population mean is not equal to 5.
The P - value is
These are both one question for me!! Ive tried this one so many times help!!

solution
(A)this is left tailed test
P(z < 2.74 ) = 0.9969
P-value = 0.9969 using z table
(B)this is two tailed test
P(z > 2.74) = 1 - P(z < 2.74 ) = 1-0.9969=0.0031*2=0.0062
P-value = 0.0062 using z table

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
