Answer:
Step-by-step explanation:
Null hypothesis 
: It is a statement about the population parameter that contains = , ≤ or ≥ signs.
Alternative hypothesis 
: It is also a statement about the population parameter but against the null hypothesis that contains = , < or > signs.
Given : The process that produces Sonora Bars (a type of candy) is intended to produce bars with a mean weight of 56 gm.
here , Population parameter = 
[ Population mean ]
i.e. 
Objective : Whether the mean is smaller than it is supposed to be.
Then, the set of hypothesis will be :
To find the average, add up all the numbers, then divide by how many numbers there are
(78 + 83 + 79) / 3 = 240/3 = 80 <== average
Percent decrease. 41%
percent change= (new-old)/old *100
= -41 % the negative means decreasing
