Find the $\mathrm{P}$-value for the indicated hypothesis test with the given standardized test statistic, $\mathrm{z}$. Decide whether to reject $\mathrm{H}_{0}$ for the given level of significance a Right-tailed test with test statistic $z=1.09$ and $\alpha=0.09$
P-value $=\square$ (Round to four decimal places as needed.)
Final Answer: The P-value is \(\boxed{0.1379}\). We do not reject the null hypothesis \(\mathrm{H}_{0}\) because the P-value is greater than the level of significance \(\alpha\).
Step 1 :Given a right-tailed test with test statistic \(z=1.09\) and \(\alpha=0.09\).
Step 2 :The P-value is the probability that a random chance generated the data, or something else that is equal or more extreme given that the null hypothesis is true.
Step 3 :In a right-tailed test, the P-value is the area to the right of the test statistic (z-score) on the standard normal distribution curve.
Step 4 :We can find this value using the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives us the area to the left of the z-score, so to find the area to the right (which is the P-value in a right-tailed test), we subtract the CDF value from 1.
Step 5 :Using this method, we find that the P-value is 0.1378565720320355, which rounds to 0.1379 when rounded to four decimal places.
Step 6 :We reject the null hypothesis H0 if the P-value is less than or equal to the level of significance (\(\alpha\)). In this case, \(\alpha = 0.09\).
Step 7 :Since the P-value is greater than \(\alpha\), we do not reject the null hypothesis H0.
Step 8 :Final Answer: The P-value is \(\boxed{0.1379}\). We do not reject the null hypothesis \(\mathrm{H}_{0}\) because the P-value is greater than the level of significance \(\alpha\).
