Transcribed Image Text:**Question 19**
Use the given information to find the P-value.
The test statistic in a two-tailed test is \( z = 1.95 \).
- 0.4423
- 0.3415
- 0.0244
- 0.0512
**Explanation:**
This question asks for the calculation of the P-value based on a given \( z \)-score in a two-tailed test. The \( z \)-score is a measure of how many standard deviations an element is from the mean. In a two-tailed test, you are checking both directions of extreme values from the mean.
To find the P-value from a \( z \)-score:
1. Use a standard normal distribution table or software to find the probability associated with the given \( z \)-score.
2. Since this is a two-tailed test, multiply the found probability by 2 to account for both ends of the distribution.
The options provided are possible values for the P-value.
