A consumer advocacy group claims that the mean amount of juice in a 16
ounce bottled drink is not 16 ounces, as stated by the bottler.
Determine the null and alternative hypotheses for the test described.
A.
H0: µ = 16 ounces Ha: µ < 16 ounces
B.
H0: µ ¹ 16 ounces Ha: µ = 16 ounces
C.
H0: µ = 16 ounces Ha: µ > 16 ounces
D.
H0: µ = 16 ounces Ha: µ ¹ 16 ounces
I have no idea what your superscript means.
For one-tailed:
Ho: µ = 16 oz
Ha: µ < 16 oz
For two-tailed:
Ho: µ = 16 oz
Ha: µ ≠ 16 oz
The correct answer is D.
The null hypothesis (H0) is a statement of no effect or no difference. In this case, the null hypothesis claims that the mean amount of juice in a 16-ounce bottled drink is equal to 16 ounces, as stated by the bottler.
The alternative hypothesis (Ha) is the opposite of the null hypothesis, stating that there is indeed a difference or effect. In this case, the alternative hypothesis claims that the mean amount of juice in a 16-ounce bottled drink is not equal to 16 ounces.
Therefore, the correct answer is:
H0: µ = 16 ounces
Ha: µ ≠ 16 ounces
