In order for a new drug to be sold on the market, the variance of the active ingredient in each dose should be 0.03mg0.03⁢mg. A random sample of 1212 tablets with a dosage strength of 40.32mg40.32⁢mg is taken. The variance of the active ingredient from this sample is found to be 0.0050.005. Does the data suggests at α=0.025α=0.025 that the variance of the drug in the tablets is less than the desired amount? Assume the population is normally distributed.

Step 1 of 5 :

State the null and alternative hypotheses. Round to four decimal places when necessary.

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.
