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 150⁢mg. A sample of 17 packages was analyzed and the sample standard deviation was 246.4609⁢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.

Step 1 of 5: State the null and alternative hypotheses. Round to four decimal places when necessary.

Step 2 of 5: Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer to three decimal places.

Step 3 of 5: Determine the value of the test statistic. Round your answer to three decimal places.

Step 4 of 5: Make the decision

Step 5 of 5: What is the conclusion?

    The nutrition label for Oriental Spice Sauce states that one package of sauce has 1160 milligrams of sodium. To determine if the label is accurate, the FDA randomly selects 80 packages of Oriental Spice Sauce and determines the sodium content. The sample has an average of 1037.92 milligrams of sodium per package with a sample standard deviation of 267.98 milligrams. Step 1 of 2 :   Calculate a 90% confidence interval for the mean sodium content in Oriental Spice Sauce.

    A laboratory claims that the mean sodium level, μ, of a healthy adult is 139 mEq per liter of blood. To test this claim, a random sample of 29 adult patients is evaluated. The mean sodium level for the sample is 142 mEq per liter of blood. It is known that the population standard deviation of adult sodium levels is 12 mEq. Assume that the population is normally_ distributed. Can we conclude, at the 0.1 level of significance, that the...
