Left tail probability table

Nettet30. aug. 2024 · Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1. First, we will look up the value 0.4 in the z-table: Then, we will look up the value 1 in the z-table: Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. NettetThe truncated t-table below shows the critical t-value. The t-table indicates that the critical values for our test are -2.086 and +2.086. Use both the positive and negative values for a two-sided test. Your results are statistically significant if your t-value is less than the negative value or greater than the positive value.

Step 2: Divide the difference by the standard deviation. SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table.

Nettet13. apr. 2024 · Here is an example of a right-tailed chi-square distribution table: 2. Using the symmetry of the chi-square distribution table, you can find the left-tail probabilities of the data. By subtracting one from the right-tail probability values of the table, you can get the left-tail probability values.
