Solution
Conduct a hypothesis test to verify if the claim that a bottle contains less than sixteen (16) ounces is supported
Null hypothesis: The bottle contains 16 ounces
Alternative hypothesis: The bottle contains less than 16 ounces
The logic is to test the significance of the difference of actual value to the hypothetical value (16)
t=(samplemean-hypotheicated mean)/SE
where SE = sd/sqrt(n) = 0.663381/sqrt(30)=0.1208
t= 15.854-16/0.1208= -1.209
Dont reject the null hypothesis
the claim is not valid.
