The process that produces sonora bars (a type of candy) is intended to produce bars with a mean weight of 56 gm. the process standard deviation is known to be 0.77 gm. a random sample of 49 candy bars yields a mean weight of 55.82 gm. which are the hypotheses to test whether the mean is smaller than it is supposed to be?

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 :

78.59 is the mean
