The value obtained for the test statistic, z, in a one-mean z-test is given. Whether the test is two-tailed, left tailed, or right-tailed is also specified. For parts (a) and (b), determine the P-value and decide whether, at the 1% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.
a) The test statistic in a left-tailed test is z=0.95
What is the P value
the P-value is ___ (round to three decimal places as needed.)
A or B a) provides or b) does not provide
A or B a) less than or b) greater than
At the 1% significance level, the data a) provides or b) does not provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because the obtained P-value is a) less than or b) greater than the significance level.
