The manufacturers of Oriental Spice Sauce are concerned that the sodium levels in their product vary too much. A package of the sauce is supposed to contain 1000 mg of sodium with a standard deviation of 50 mg. A sample of 30 packages was analyzed and the sample standard deviation was 51.1691 mg. Is there evidence at α = 0.025 that the standard deviation of the sodium content exceeds the desired level? Assume the population is normally distributed.
