Question

Find the critical value zc necessary to form a confidence interval at the level of confidence c=0.94

Answers

  1. The critical value of Z at the level of confidence c=0.94 is z = 1.91.
    According to the statement
    we have given that the a confidence interval at the level of confidence c=0.94. And we have to find the critical value of the z.
    So, For this purpose, we know that the
    Critical value can be defined as a value that is compared to a test statistic in hypothesis testing to determine whether the null hypothesis is to be rejected or not.
    So, The given confidence interval is 0.94
    Then
    1- 0.94 = 0.6.
    So, critical value for the 0.6 according to the table is
    z = NORM SINV(.06/2)= 1.9112
    And we know that the
    The value of z with given confidence interval is
    90%
    z =1.645
    92%
    z = 1.751
    95%
    z = 1.96
    98%
    z = 2.326
    So, The critical value of Z at the level of confidence c=0.94 is z = 1.91.
