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:

Semenov [28]

Answer:

a(8a-1)(3a+5)

Step-by-step explanation:

24a³ + 37a² – 5a =

a ( 24a²+ 37a -5) =

a( 24a² +40a -3a -5) =

a [8a(3a+5) -1(3a+5) ]=

a(8a-1)(3a+5)
