Question

Express the null hypothesis and the alternative hypothesis in symbolic form.

Use the correct symbol (μ,p,σ) for the indicated parameter.

A cereal company claims that the mean weight of the cereal in its packets is at least 14 oz.

a. H0: μ<14
H1: μ≥14

b. H0: μ=14
H1: μ<14

c. H0: μ>14
H1: μ≤14

d. H0: μ=14
H1: μ>14

Answer 1

Answer:

a. H0: μ<14

H1: μ≥14

Step-by-step explanation:

Mean symbol:

The mean symbol is given by $\mu$

A cereal company claims that the mean weight of the cereal in its packets is at least 14 oz.

At the null hypothesis, we test if the proportion is of less than 14 oz, that is:

$H_0: \mu < 14$

At the alternative hypothesis, we test if this proportion is of at least 14 oz, that is:

$H_1: \mu \geq 14$

So the correct answer is given by option a.
