In an effort to make a healthier product, the Oriental Spice Sauce company has reduced the amount of sodium in their product to 900mg900⁢mg. In addition, the standard deviation of the amount of sodium should be 140140. To make sure this new product continues to meet the standard, a random sample of 2323 bottles is taken, and the standard deviation for the sample was 211.4017211.4017. Is there evidence at α=0.1α=0.1 that the standard deviation of the sodium content exceeds the desired level? Assume the population is normally distributed.

Step 3 of 5 :

Determine the value of the test statistic. Round your answer to three decimal places.

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.
