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...
A manufacturer of nickel-hydrogen batteries randomly selects 100 nickel plates for test cells, cycles them a specified number of times, and determines that 12 of the plates have blistered. (a) Does this provide compelling evidence for concluding that more than 10% of all plates blister under such circumstances? State and test the appropriate hypotheses using a significance level of 0.05. Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to...

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...

Olestra is a fat substitute approved by the FDA for use in snack foods. The article Gastrointestinal Symptoms Following Consumption of Olestra or Regular Triglyceride Potato Chips (Journal of the American Medical Association, 1998: 150-152) reported that in an experiment, 17.6% of the 529 individuals in the TG control group experience an adverse GI event, whereas 15.8% of the 563 individuals in the olestra treatment group experienced such an event. Does it appear that the incident rate of GI problems...
