The following table displays the most common critical values for different values of α: The way to interpret this table is as follows: For a test using a 90% confidence level (e.g. α = 0.1), the z critical value is 1.645. For a test using a 95% confidence level (e.g. α = 0.05), the z critical value is 1.96. The conditions for inference are met and so the confidence interval is. 𝑥̅ ± 𝑧* ∙ 𝜎∕√𝑛 =. = 749 ± 1.96 ∙ 32∕√36 ≈. ≈ (738, 760) This means that we are 95% confident that the population mean is within this interval. It doesn't tell us anything about the shape of the population distribution though.Here are the steps to use this calculator: First, enter the value for the Degrees of Freedom. Then, enter the value for the Significance level. This value should be between 0 and 1 only. After entering these values, the T score calculator will generate the T value (right-tailed) and the T value (two-tailed).Question: Use StatCrunch to find the critical value ∗ for the following situations. a) a 98% confidence interval based on df=17 b) a 90% confidence interval based on df=71. a) What is the critical value of t for a 98% confidence interval with df=17 ? (Round to two decimal places as needed.).
