Question

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 450 gram setting. It is believed that the machine is underfilling the bags. A 1414 bag sample had a mean of 447grams with a variance of 289. Assume the population is normally distributed. A level of significance of 0.05 will be used. Specify the type of hypothesis test.

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 428 gram setting. It is believed that the machine is underfilling or overfilling the bags. A 13 bag sample had a mean of 424 grams with a variance of 169. Assume the population is normally distributed. A level of significance of 0.01 will be used. Specify the type of hypothesis test.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
