According to a chips company, the mean weight of a bag of its "pams" tortilla is 5 oz.

A consumer advocate believes that the mean weight is actually less than 5 oz.

A random sample of 50 bags of "pams" chips was tested. And the mean weight for the sample was 4.9 oz. w/ a sample standard deviation of 0.4 oz.

Does the sample data support the consumer advocates claim that the mean weight of the pop. is less than 5 oz. ? Use the .05 significance level. Be sure and address these items: null and alternate hypothesis, test statistic, critical values, conclusion, p value
