Brand ways Company indicate on the label that their loaves weigh 500g. A sample of 50 loaves is selected hourly from their processing line and the contents weighed. Last hour a sample of 50 loaves had a mean weight of 503g with a standard deviation of 13g. Test at 0.05 significance level whether their process is out of control?

Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let u denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (7.1, 9.8). (a) Would a 90% confidence interval calculated from this same sample have been narrower or wider than the given interval? Explain your reasoning. The 90% would be wider...

A random sample of 50 bottles of a brand of cough syrup is selected, the alcohol content of each bottle is calculated Let μ be the average alcohol content for the population of all bottles of the brand under consideration. The resulting 95% confidence interval is (7.8,9.4) (a) Would a 90% confidence interval calculated from the same sample be wider or narrower? Explain. (b) Consider the statement: there is a 95% chance that is between 7.8 and 9.4. Is this correct? Explain. (c)...

Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected
Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected, and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (8.0, 9.6).a. Would a \(90 \%\) confidence interval calculated from this same sample have been narrower or wider than the given interval? Explain your reasoning.b. Consider the following statement:...

Each person in a large sample of German adolescents was asked to
indicate which of 50 popular movies they had seen in the past year.
Based on the response, the amount of time (in minutes) of alcohol
use contained in the movies the person had watched was estimated.
Each person was then classified into one of four groups based on
the amount of movie alcohol exposure (groups 1, 2, 3, and 4, with 1
being the lowest exposure and 4...

A company has 189 accountants. In a random sample of 50 of
them, the average number of overtime hours worked in a week was 9.7
and the sample standard deviation was 6.2 hours.
a) Find a 95% confidence interval of the average number of
overtime hours worked by each accountant in this company during
that week.
b) Find a 99% confidence interval of the total number of
overtime hours worked by each accountant in this company during
that week.
The President Of A Company States That The Average Hourly Wage Of Her Employees Is $8.65. A Sample Of 50 Employees Has The Distribution Shown. At α=0.05, Is The President’s Statement Believable? (Use S To Approximate σ.)
To determine whether the President's statement that the average hourly wage of her employees is $8.65 is believable or not, we need to perform a hypothesis test.
