Use the given information to find the P-value. Also, use a 0.05 significance state the conclusion about the null hypothesis (reject the null hypothesis c reject the null hypothesis). The test statistic in a left-tailed test is z = -1.83. O 0.0672; reject the nuli hypothesis O 0.0336; reject the null hypothesis 0.9664; fail to reject the null hypothesis 0.0672; fail to reject the null hypothesis

Suppose we want to test the null hypothesis Ho : p = 0.34 against the alternative hypothesis H1 : p > 0.34. Suppose also that we observed 120 successes in a random sample of 300 subjects and the level of significance is 0.05. What is the observed test statistic for this test? Select one: а. -2.194 b. 0.4 C. 2.194 d. 0.05

A hypothesis test is performed in a study of AirBnB's to learn about the proportion of them that have 4 televisions. The null and alternative hypotheses are as followed: Null: p=0.13 Alternative: p<0.13 Researchers had determined that 39/500 randomly selected airbnb's had 4 televisions. Once all of the necessary conditions were verified for a statistical inference, the researchers correctly calculated the P-Value to be approximately 2.7269x10^-4 a) Please use the appropriate symbols and values to communicate the specific conditional probability that the P-Value represents in the context of this study. b) In a sentence or two, describe the specific event in the context of this study which has probability equal to the P-Value of occuring. c) When the P-Value in this hypothesis test is rounded and expressed with 3 digits after the decimal point (0.000) does it mean that the event described in part (b) has no chance of occurring? Explain in one to two sentences.

Find the P-value for a left-tailed hypothesis test with a test statistic of z= -1.02. Decide whether to reject Ho if the level of significance is α = 0.05. P-value= (Round to four decimal places as needed.) C

We are testing a null hypothesis Ho:P1=P2 against an alternative hypothesis H7:P1 P2 where n = 50, x1 = 11, and n2 = 75, x2 =24. Find the value of the test statistic. 1.22 -1.89 -1.22 -.99

The test statistic of z = 2.05 is obtained when testing the claim that p > 0.4. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. Find the P-value. Using a significance level of α = 0.10, should we reject H0 or should we fail to reject H0?

Find the​ P-value for the indicated hypothesis test with the given standardized test​ statistic, z. Decide whether to reject H0 for the given level of significance α.   ​Two-tailed test with test statistic z=−1.86 and α=

Suppose there is a claim that a certain population has a mean, H, that is different than 5. You want to test this claim. To do so, you collect a large random sample from the population and perform a hypothesis test at the 0.10 level of significance. To start this test, you write the null hypothesis, Ho, and the alternative hypothesis, H1, as follows. Hg: u= 5 H1: u=5 Suppose you also know the following information. The value of the test statistic based on the sample is 1.506 (rounded to 3 decimal places). The p-value is 0.132 (rounded to 3 decimal places). (a) Complete the steps below for this hypothesis test. Standard Normal Distribution 04 Step 1: Select one-tailed or two-tailed. O One-tailed O Two-tailed 0.3+ Step 2: Enter the test statistic. (Round to 3 decimal places.) 0.2 Step 3: Shade the area represented by the p-value. 0.1+ Step 4: Enter the p-value. (Round to 3 decimal places.) ? (b) Based on your answer to part (a), which statement below is true? Since the p-value is less…

B. Calculate the value of the test statistic. χ2=____   C. Use technology to determine the​ P-value for the test statistic.   The​ P-value is______   D. What is the correct conclusion at the α=0.10 level of​ significance? Since the​ P-value is(greater or less)than the level of​ significance. (Do not reject or reject) the null hypothesis. There (is or is not) sufficient evidence to conclude that the standard deviation of heights of​ major-league baseball players is less than 2.4 inches at the 0.10 level of significance. ​

The test statistic of z = 0.53 is obtained when testing the claim that p > 0.5. Identify the hypothesis test as being​ two-tailed, left-tailed, or​ right-tailed. Find the​ P-value. Using a significance level of α = 0.05​, should we reject H0 or should we fail to reject H0​?
