We have given-

The average alcohol content of red wine is 10.423, while that of white wine is 10.5143. The respective standard deviations are 1.0657 and 1.2306. The respective sample sizes are 1599 and 4898.

the difference between means.

Mean of Red wine - White wine

10.423 - 10.5143 = - 0.0913

A sample of wine was diluted 1:10 and analyzed for alcohol content. A calibration curve was created from a set of standard solutions producing a plot of absorbance vs. percent alcohol. The calibration curve had a slope of 8.07 x 10-2 with an intercept of 6.02 x 10-3. Keeping in mind that the wine sample was diluted by a factor of ten, what is the percent, by volume, of alcohol in your sample if the absorbance of your sample was...

The ICU-Admissions dataset includes a variable indicating the age of the patient. Find and interpret a 90% confidence interval for mean age of ICU patients using the facts that, in the sample, the mean is 55.75 years and the standard error for such means is SE = 1.64. The sample size of 100 is large enough to use a normal distribution

A breath analyzer is used by the police to estimate blood alcohol content (BAC) from a breath sample. If a person’s BAC is above (or equal to) the legal limit, they can be arrested for suspicion of driving while impaired from alcohol. However, the only way to accurately measure BAC level is through taking a blood sample; a number of factors are known to influence the results of breath analyzers, such as hypoglycemia. A particular brand of breath analyzer is...

In this chapter we suggested that whenever market price fell below average variable costs, the firm will shut down. At that point, revenue is not covering its variable costs and the firm is losing more money than it would if it shut down and lost its fixed costs. Clearly, shutting the firm down is more complicated than that. Under what circumstances might the firm continue to operate even though prices are below average variable costs? a. It would not continue...
