Question

It is known that the volume of containers of a specific lubricant is normally distributed with a variance of 0.03 liters. Test the hypothesis that o^2 is not equal to 0.03 for the random sample of 10 containers with s = 0.24585 l. Use a P-value in your conclusions.

Note:
In the image, this is the exercise in Spanish, which is the original, to make it more understandable.

Se sabe que el volumen de los envases de un lubricante específico se distribuye
normalmente con una varianza de 0.03 litros. Pruebe la hipótesis de que o2 = 0.03 contra la
alternativa de que o? # 0.03 para la muestra aleatoria de 10 envases con s = 0.24585 Its. Use un

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.
