Find the critical value x2r corresponding to a sample size of 19 and a confidence level of 99% if the test is two-tailed

iragen [17]

Answer:

For this problem we are assuming that the confidence level is 99% or 0.99, then the significance level would be $\alpha=0.01$ then the value of $\alpha/2 =0.005$ and the degrees of freddom are given by:

$df =n-1 = 19-1=18$

Then the critical values for this case are:

$\chi^2_{\alpha/2}=6.265$

$\chi^2_{1-\alpha/2}=37.156$

Step-by-step explanation:

Ierofanga [76]

First point to be noted here is, the shelf and the book are 5 inches wide. So it is perfect to hold the book.

The shelf is 56 inches tall and the book is 4 inches thick. To find the number of books Linda can arrange on the shelf, just divide 56 by 4

Number of books Linda can arrange on the shelf = 56 ÷ 4 = 14 books
