show all solution A wine’s distinctive taste is a result of ageing it in wooden casks. Some of the wine evaporates while it is aging in the porous wooden casks. Define X=percentage of wine in the cask that is lost due to evaporation. Suppose X is normally distributed with mean 5% and a standard deviation of 1%. What is the probability of losing more than 7.5% of the wine due to evaporation?
Find the standard error of the sample mean such that we have 60 random samples with mean 25 and standard deviation of 13. (Round to 3dp)
Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma.+ Over a period of months, an adult male patient has taken eleven blood tests for uric acid. The mean concentration was x = 5.29 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with o = 1.87 mg/dl. (a) Find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error (b) What conditions are necessary for your calculations? (Select all that apply.) o is known o is unknown normal distribution of uric acid O uniform distribution of uric acid On is large (c) Interpret your results in the context of this problem. O We are 5% confident that the true uric acid level for this patient falls within this interval. O We are 95% confident that the…

A normal shaped distribution with mean of 40 and standard deviation of 8 is transformed into z-score. Describe the shape, the mean, and the standard deviation for the resulting distribution of z-score.

USE 3 DECIMAL A producer claims that his potato chips weight has a normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams. If manager want to test the claim as night shift mean weight of the product is greater than that of day shift at 1% level of significance. Calculate the test statistics. (H1: m night shift > m day shift).
