a random sample of cereals obtained the sugar content for the 16 cereals has a mean of 295 grams and a std deviation of 0.168 grams. If we wished to test the claim that the mean for all cereals is less than 0.300 grams, which of the following is the appropiate test?
a) two tail z test
b) two tail t test
C)left tail z test
d) left tail t t test'
e) right tail t test
Homework Answers
We need to test whether mean is less than 0.300 and the population standard deviation is unknown. So,
We will use left tail t test here.
Option D is correct.
