Transcribed Image Text:Problem Solving: Caselet 1
A store that sells LPG claims that the mean weight of their mini-tanks are exactly 6-kgs as prescribed. Using a
random sample of 15 mini LPG tanks, a regular customer tests the theory that the average weight of the store's
tanks are somehow lower than the prescribed weight. Use a significance level of a=0.10

What is the null and alternative hypothesis? *
The mean weight of mini LPG tanks IS EQUAL TO 6-kg. (u = 6-kg): The weight of mini LPG tanks DOES NOT
EXCEED 6-kg. (p < 6-kg)
The mean weight of mini LPG tanks IS EQUAL TO 6-kg. (u = 6-kg): The mean weight of mini LPG tanks
EXCEEDS 6-kg. (p > 6-kg)
The mean weight of mini LPG tanks IS EQUAL TO 6-kg (u = 6-kg): The mean weight of mini LPG tanks IS NOT
EQUAL TO 6-kg. (u = 6-kg)
