For example, a canned drink with the brand "BOBA" has an average net weight of 350 ml written on the can. But lately there are allegations that the net weight has decreased. Then the owner of the company took a random sample of 100 cans of canned drink, and it turned out that the random sample came from a normal distribution with an average of 349,5 ml and a standard deviation of 1,75. Is the assumption above correct? Use significant level=10%. Try writing it down as follows:

a. Formulating statistical hypotheses

b. Finding significant level

c. Finding the critical area

d. Calculating statistical value

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.
