A nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium* franks. The mean sodium content for the sample was 321.9 mg with a standard deviation of 19 mg. Assume that the assumptions and conditions for the test are met. a) Test the hypothesis that the mean sodium content meets the regulation. b) Will a larger sample size ensure that the regulations are met?...

A nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks. The mean sodium content for the sample was 322.3 mg with a standard deviation of 17 mg.

A nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks. The mean sodium content for the sample was 321.6 mg with a standard deviation of 19 mg. Choose the appropriate null and alternative hypotheses A. H0: u=325 HA: u<325 B. H0: u=325 HA: u=321.6 C. H0: u=325 HA: u does not equal 325 (its the equal sign with a slash in it)...

1. A nutrition laboratory randomly selected and tested 26 reduced sodium hot dogs. It was found that their average (mean) sodium content is 310 mg with the standard deviation of 54 mg. It is known that the distribution of the sodium contents in this brand of hot dogs is approximately normal. What is a t* for a 90% confidence interval for the average (mean) sodium content of this brand of hot dogs? Round your answer to 4 decimal places. 2.A...

Cadmium, a heavy metal, is toxic to animals. Mushrooms, however, are able to absorb and accumulate cadmium at high concentrations. A government set a safety limit for cadmium in dry vegetables at 0.5 parts per million (ppm). The cadmium levels in a random sample of one species of edible mushroom are in the accompanying data set. At the 10% significance level, do the data...
