Question 1177609
with assumptions of normality, etc.
Ho: mean is >=32 oz
Ha: mean < 32 oz, using a right tail test, since there is a suspicion of cheating, rather than not 32 oz. 
alpha=0.01 prob {reject Ho|Ho true}
test is a t 0.995 df=49
critical value |t|>2.405
test statistic is t= (xbar-mean)/s/sqrt(n)
=-0.6*sqrt(50)/1.75
=2.42
Reject null hypothesis at the 0.01 level for this one tail test and supports the claim.
p-value=0.00953
