Amanufacturer of banana chips would like to know whether its bag filling machine works correctly at the 431 gram setting. it is believed that the machine is underfilling the bags. a 23 bag sample had a mean of 430 grams with a standard deviation of 24. a level of significance of 0.025 will be used. assume the population distribution is approximately normal. state the null and alternative hypotheses.

Step-by-step explanation:

Given : A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 431 gram setting. t is believed that the machine is underfilling the bags.

Claim :

We know that the null hypothesis always have equals sign , then the required set of hypothesis for the situation :-

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:
