x + 2x - x - 1
- Substitute 2 for x into the expression.
(2) + 2(2) - (2) - 1
(2) + (4) - (2) - 1
- Solve from left to right.
- (2 + 4) - 2 - 1 = 6 - 2 - 1
6 - 2 - 1
- Solve from left to right.
- (6 - 2) - 1 = 4 - 1
4 - 1 = 3

Answer:
H0 : p = 0.75
H1 : p ≠ 0.75
Step-by-step explanation:
The population proportion, P0 = 0.75 ;
Claim is that proportion of customers who use online coupons when making purchases is actually different than P0 = 0.75 (this is the calm) and the difference could be either more or less
Hence, the null hypothesis H0 : says P0 is 0.75 ;
H0 : p = 0.75
The alternative hypothesis, negating the null hypothesis argues that the proportion is not 0.75 (the difference could be either to the right or left).
H1 : p ≠ 0.75
