According to the production supervisor of XYZ Food Corporation, the mean weight of CHEESE Curls packed by the machine is 56 grams, with a population standard deviation of 8.5 grams. The person in charge in the production believes that the average amount is not equal to 56 grams. He randomly selected 49 packs of the product and found out that the mean weight is 54 grams. Test this claim at α = 0.05 level of significance. The null hypothesis can be constructed mathematically as; Ho : μ ≠ 56 Ho : μ ≠ 54 Ho : μ = 56 Ho : μ > 54 The mathematical notation of the alternative hypothesis is; Ha : μ ≠ 54 Ha : μ ≠ 56 Ha : μ > 54 Ha : μ < 56

According to the production supervisor of XYZ Food Corporation, the mean weight of CHEESE Curls packed by the machine is 56 grams, with a population standard deviation of 8.5 grams. The person in charge in the production believes that the average amount is not equal to 56 grams. He randomly selected 49 packs of the product and found out that the mean weight is 54 grams. Test this claim at α = 0.05 level of significance. The null hypothesis can be constructed mathematically as;
Ho : μ ≠ 56
Ho : μ ≠ 54
Ho : μ = 56
Ho : μ > 54
The mathematical notation of the alternative hypothesis is;
Ha : μ ≠ 54
Ha : μ ≠ 56
Ha : μ > 54
Ha : μ < 56
