Answer:

Less than 25%

Step-by-step explanation:

1. Find the difference of the two numbers: 1,207 - 957 = 250

decrease = original number - new number

2. Then, divide the decrease by the original number

250/1,207 = 0.207

3. Multiply the answer by 100 to get the percentage

0.207 x 100 = 20.7%

Therefore, the number of people fell by 20.7%

Hence, the answer is less than 25%

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:
