Null hypothesis: 
Alternative hypothesis: 
The null is based on a recent study that 81% of the population (in this case senior citizens) takes at least one medication. The alternative hypothesis is basically the flip of the claim made in the null.
If Amelia wanted to know if the percentage was less than 81%, then the alternative would be p < 0.81
If Amelia wanted to know if the percentage was larger than 81%, then the alternative would be p > 0.81
However, she wants to know if the percentage is 81%.

Answer:
x ≥ 767
The number of bags sold must be greater than or equal to 767 to make a minimum profit of $6900.
Step-by-step explanation:
If they want a profit of at least $6900, then the total amount earned would have to be ≥ 6900. You can always earn more than $6900, but the lowest should be equal to $6900.
So if we use x as the number of bags sold, and we know that each bag will earn $9, then x • 9 ≥ 6900.
If we divide both sides by 9, then the number of bags sold must be ≥ 767.
