Answer:
The p-value for two-tailed test is 0.136
Step-by-step explanation:
Given;
one-tail test, p-value = 0.068,
In one-tailed test, we test for the possibility of a relationship in one direction and completely disregard the possibility of a relationship in the other direction.
One-tail test provides possibility of an outcome in one direction, while
two-tail test provides possibility of an outcome in two different directions.
Thus, the p-value for two-tailed test = 2 x 0.068 = 0.136
Answer:
He needs 7 buckets of cement, and 28 buckets of sane.
Step-by-step explanation:
cement : sand
1:4 = 5
35/5 = 7
7*1=7 . Cement
7*4=28 . Sand
148, 6-1.75=5.25, then.... 625/5.25& round up.... its 148.
68 because it is a perpendicular bisector we can assume that the angles full length is 90 degrees meaning you can just do 90-22=68
