Alternative hypothesis:
Statistic
P value
The p value for this case would be given by:
Conclusion

Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value to verify
represent the significance level
t would represent the statistic
represent the p value for the test
Hypothesis to verify
We want to cehck if the true mean is 12 or not, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Statistic
The statistic is given by:
(1)
Replacing the info given we got:
The degrees of freedom are given by:
P value
The p value for this case would be given by:
Conclusion
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly different from 12 oz.
