A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g.

Let μ be the mean weight of the burritos at this restaurant and x be the mean weight of the burritos in the sample.

Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:

a. H₀ : x = 250 g
Hₐ : x < 250 g

b. H₀ : x = 250 g
Hₐ : x > 250 g

c. H₀ :μ = 250g
Hₐ :μ < 250g

d. H₀ :μ = 250g
Hₐ :μ > 250g
