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.

C.
H0: µ = 16 ounces Ha: µ > 16 ounces

D.
H0: µ = 16 ounces Ha: µ ¹ 16 ounces

Answer 1

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
