The critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
<h3>How to determine the critical values corresponding to a 0.01 significance level?</h3>
The scatter plot of the election is added as an attachment
From the scatter plot, we have the following highlights
- Number of paired observations, n = 8
- Significance level = 0.01
Start by calculating the degrees of freedom (df) using
df =n - 2
Substitute the known values in the above equation
df = 8 - 2
Evaluate the difference
df = 6
Using the critical value table;
At a degree of freedom of 6 and significance level of 0.01, the critical value is
z = 0.834
From the list of given options, 0.834 is between -0.881 and 0.881
Hence, the critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881

Answer:
x= 1/3 =0.333
Step-by-step explanation:
change to improper fractions
42 1/3
(3* 42 +1) /3 = 127/3
1 1/3 = (3*1 +1) /3 = 4/3
127/3 divided by 4/3
copy dot flip
127/3 * 3/4
127/4
31 3/4 miles per hour
He drove 31 3/4 miles in one hour
31 3/4 miles 1 mile
------------ = ------------
1 hours x hour
using cross products
31 3/4 * x =1*1
x = 1/ 127/4 (copy dot flip)
x = 1 * 4/127
x = 4/127
it takes 4/127 of 1 hour (approx .03 hours)
