USE 3 DECIMALS A producer claims that his potato chips weight has a normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams.If manager want to test the claim as night shift mean weight of the product is less than that of day shift at 1% level of significance. Calculate the test statistics. (H4 night shift

Question
USE 3 DECIMALS A producer claims that his potato chips weight hasa normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams. If manager want to test the claim as night shift mean weight of the product is less than that of day shift at 196 level of significance. Calculate the test statistics. (H: night shift <H day shift).
