The p-value (denoted p) for a set of data is the probability that the given data (or something even more unusual) would occur if the hypothesis being tested is not true. How do you find p-value from z-statistic? To calculate the p-value, first find the test statistic, a value that...
Answer to: Use the given information to find the P-value. The test statistic in a two-tailed test is z = 1.30. By signing up, you'll get thousands...
Use Z-table to find p-value, if the test value for the left sided test is found to be -2.15. - 0.9842 - 0.0158 - 0.0316 - 0.765 P-Value: The p-value is the area of the tail beyond the calculated value of the test statistic. If...
Question: 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.Right-tailed test with test statistic z=1.67 and α=0.05P-va...

Given a mean of 52.3 and a standard deviation of 1.8. What is the z-score of the value 51.8 rounded to the nearest tenth? Suppose the test scores of students in a class are normally distributed with a mean of 86 and a standard deviation of 4. What is the z...
The ABS function adjusts the T value for a right-tailed test. The T and Z critical values differ from the T and Z values. We calculate the T and Z values from the sample statistic and population parameters. Then we compare those values with the critical values to determine the statistica...
Step 2: Look up the value you calculated in Step 1 in the z-table and find the corresponding z-value. The z-value that has an area of .475 is 1.96. Step 3: Divide the number of events by the number of trials to get the “P-hat” value: 24/160 = 0.15. Step 4: Plug your ...

There is evidence that lower height is associated with a higher risk of coronary artery disease (CAD) and increased risk of type 2 diabetes (T2D). It is not clear though whether these associations are causal, direct or mediated by other factors. Here we
