A company sells cans of caviar that say they each contain 100g of product. a consumer advocacy group suspects that the company is under-filling these cans. the group obtains a sample of cans and measures how much product is in each can. they calculate a sample mean of 99g and a sample standard deviation of 1g. they will take further action if this is significantly lower than the advertised amount. let π represent the mean amount of product in all cans of this type. which of the following is an appropriate set of hypotheses for their significance test?
a. H0 : π = 99g
Hs : π < 99g
b. H0 : π = 100g
Hs : π < 100g
c. H0 : π = 99g
Hs : π < 100g
d. H0 : π = 100g
Hs : π < 99g
