. You have an SRS of 23 observations from a large population. The distribution of sample values is roughly symmetric with no outliers. What critical value would you use to obtain a 98% confidence interval for the mean of the population? (a) 2.177 (b) 2.183 (c) 2.326 (d) 2.500 (e) 2.508

(e) 2.508

Step-by-step explanation:

n = 23

degree of freedom = n - 1 = 23 - 1 = 22

confidence level = 98%

Using the t-distribution table, critical value for 22 degrees of freedom and 98% confidence level is 2.508

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
