Acompany advertises that there are an average of 25 grams of potato chips in each bag of chips. a consumer group has collected a sample and wants to perform a test to see if the company is providing less than it advertises. h0: μ = 25 ha: μ < 25 which type of significance test should be used for this situation?

one sample t-test will be appropriate in this case

Step-by-step explanation:

We are carrying out a hypothesis test of the mean with the population standard deviation being unknown. We shall estimate the population standard deviation with the sample equivalent, s in determining the value of the test-statistic.

we don't have enough info to solve this

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
