A package 1080 milligrams of sodium. to determine if the label is accurate, the fda randomly selects 120 package of oriental spice sauce and determines the sodium content. the sample has an average of 1154.13 milligrams of sodium per package with a sample standard deviation of 242.02 milligrams.
Step 1: calculate a 90% confidence interval for the mean sodium content in oriental spice sauce
Step 2: choose the correct one
a. hypothesized value falls in the interval, fail to reject the null. not sufficient evidence
b. hypothesized value falls in the interval, we reject the null. there is sufficient evidence
c. hypothesized value does not fall inside the interval, we reject the null. there is not sufficient evidence
d. hypothesized value does not fall inside the interval value, we reject the null. there is sufficient evidence.

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.

In order to ensure the consistency of their product, the Oriental Spice Sauce company has a strict policy that the standard deviation of the sodium content in the product is 140mg. For one size of bottle, the sodium content is supposed to be 900mg. In a random sample of 11 bottles, the standard deviation was found to be 275.4444mg. Is there evidence at α=0.01 that the standard deviation of the sodium content exceeds the desired level? Assume the population is...

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 1000mg of sodium with a standard deviation of 150mg. A sample of 17 packages was analyzed and the sample standard deviation was 246.4609mg. 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...

The average daily volume of a computer stock in 2011 was u = 35.1 milion shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of 40 trading days in 2014, he finds the sample mean to be 25,3 million shares with a standard deviation of s 12.1 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parts (a) through...
