Critical value for 98 confidence interval
The confidence level refers to the long-term success rate of the method, that is, how often this type of interval will capture the parameter of interest. A specific confidence interval gives a range of plausible values for the parameter of interest. Let's look at a few examples that demonstrate how to interpret confidence levels and confidence ...If your table doesn't have the exact degrees of freedom, defer to the next smaller one on the table. Suppose we take a sample of size 65. What is the critical value for a 98% confidence interval? If your table doesn't have the exact degrees of freedom, defer to the next smaller one on the table. There are 2 steps to solve this one.

The z * -val For a 95% confidence level, the Z-score is approximately 1.96. This means that if your data is normally distributed, about 95% of values are within 1.96 standard deviations of the mean. Similarly, for a 99% confidence level, the Z-score is approximately 2.576.
