Answer:
[tex]H_o:\mu\geq 430\\\\H_a:\mu<430[/tex]
Step-by-step explanation:
-let [tex]\mu[/tex] denote the population mean in grams.
-The claim under investigation is that the machine is underfilling the bags.
-The investigator intends to determine whether or not the population mean is less than 430 grams.
#The stated hypotheses are:
The null hypothesis(mean gram of the bags is greater or equal to 430g):
[tex]H_o:\mu\geq 430\\\\[/tex]
-Alternative hypothesis is the population mean is less than 430g:
[tex]H_a:\mu<430[/tex]
