Answer:  H_0:\mu=421

H_a : \mu\neq421

Step-by-step explanation:

  • A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.

Given: A 37 bag sample had a mean of 421 grams.

Then, the null hypothesis would be:

H_0:\mu=421

whereas the alternative hypothesis would be:

H_a : \mu\neq421
