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)
D. H0: u=325
HA: u>325
E.H0: u does not equal 325
HA: u<325
F. H0: u<325
HA: u is greater than or equal to 325

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...

00 Usman Haruna: Attempt 1 Use the following information for problems 9 16: Atrazine is a herbicide that selectively controls several species of weeds without harming crops. It is widely used on corn in the Gallatin Valley. If the atrazine concentration is too high, the herbicide has the potential to cause weight loss, cardiovascular damage, retinal and some muscle degeneration, and mammary tumors. Environmental Protection Agency (EPA) researchers measured atrazine concentrations (in mg/L) in both June and September at a...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
