Do the following: a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the $P$ -value. (See Figure $8-3$ on page $364 .$ ) c. Using a significance level of $\alpha=0.05,$ should we reject $H_{0}$ or should we fail to reject $H_{0} ?$ The test statistic of $z=2.01$ is obtained when testing the claim that $p \neq 0.345.$
Now. This time I have my value as minus 1.94 My Z statistic is minus 1.94 My Alfa is 0.5 Alfa is 0.5 and I want it is the claim that P is equal to 3.8. So in this case, he is equal to three by eight, not three point, they just buy it. This will again be a to tail test. Right? Because if this is my null hypothesis, my alternative will be that he is not equal to three by it. And since I have a not equal to sign, this will be a two tailed test to feel best. Now for there is equal to minus 1.94 What is my be value myself is minus 1.94 This is a two tailed tests. So what is my value? The value that I get in this case is 0.523 My P value is 0.523 And since my P values greater than Alfa, I say that I do not have enough evidence to reject Mandel hypothesis. So I fail to reject Mandel hypothesis
Now, in this question, my distant Asti is minus 2.5 Z value is minus 2.5 and I want to check for the claim that he is less than 0.75 p is less than 0.75 somewhere. Here, I have minus 2.5. Okay, this is going to be a left tail. As since this is a less than claim. This is going to be a left tail. A single tail on the left tail test. What is my Alfa my Alfa 0105? Okay, so let's try to find the P value for minus 2.5 for minus 2.5 minus 2.5. The P value that I'm getting 0.60 point 60.6 And my Alfa is 0.5 And as I can see that my P value is less than my Alfa. I say that I have enough statistical evidence to reject my null hypothesis. So I reject Mindulle hypothesis. H not
All right. In this case, we have been given that the set score is 1.0 and we're testing for the claim that he is greater than zero. Sorry is please greater than 0.3 if he is greater, which means that there's a single tail test and a right ale test. Right? We're going to shape for this region. Okay, ourselves statistic is 1.0 R Alfa level for this question is 0.5 And if I check the P value for that is equal to 1.0, I find that my P value is 0.158 Right? And since my people is greater than Alfa, I say that I do not have enough statistical evidence toe reject Mindulle hypothesis. This is not a significant. It is all right. Statistically significant result. And this would be my answer
Yeah we want to conduct the following test that after equals 0.5 immigrants. We want to test whether P one does not equal P two for example data X one and one X two M two. That is we want to conduct the test of the difference of population proportions P one and P two. To conduct this hypothesis test, we need to proceed with steps A through E. Listen to well first and a. We state our hypotheses this is H. R proportions are equal. If you want to speak to H one H A P one does not equal P. Two and P we can create our test steps. We have P hat one equals X. Number N one. We have to be the next to other into full P had equal 12 consecutive over and want them to be eating these numbers into our test statistic gives me not equals 19.3 point four are critical value at 5% significance in the table is er over 200 plus and minus 1.96 The P value is P equals two pc. Grieving after values are not equal 20.73 dust. We have an E that since P is greater than alpha and Xena is not in the critical region, we failed to reject the null hypothesis H nine.
