B
Step-by-step explanation:
Absolute value works like this.
For any number you put inside the absolute value bars, it will always come out positive, so -5 and 5 can work.
5/8 = 20/32
if you multiply the denominator and the numerator of 5/8 by 4 it will equal 20/32
yes {(1, 1), (2, 2), (3, 3), (4,4)}
{no (1, 6), (9, 3), (6, 1), (3, 9)}
yes {(1,2), (3, 4), (5, 6), (1, 3}
no {(7,5), (-3, 7), (-7, 5), (-3,5)}b
I think it's correct
a. What is the standard error of the sample proportion who find this offer attractive? = 0.0351
b. What is the probability that the sample proportion is more than 0.15? = 0.9222
c. What is the probability that the sample proportion is between 0.18 and 0.22? = 0.4314
