Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. A representative of a consumer advocate group wishes to see if there is any evidence that the mean net weight is less than advertised and plans to construct a 95% confidence interval for the mean, using an SRS of 16 bags. Suppose he is not sure if the distribution of net weights is Normal. In which of the following circumstances would he not be safe to use a t procedure?
The mean and median of the data are nearly equal.
A histogram of the data has a single peak and is roughly symmetric.
A stemplot of the data has a large outlier.
The sample standard deviation is large.
None of these circumstances would prevent us from using t procedures.
