A sample of 20 glass bottles of a particular type was selected, and the internal pressure strength of each bottle was determined. Consider the following partial sample information.
- median = 202.7
- lower fourth = 197.0
- upper fourth = 217.5
| Three smallest observations | 125.6 | 187.9 | 194.1 |
|---|---|---|---|
| Three largest observations | 220.1 | 230.1 | 251.1 |
(a)
Are there any outliers in the sample?
Yes/No
Any extreme outliers?
Yes/No
(b)
Construct a boxplot that shows outliers.
Comment on any interesting features.
There is a bit of positive /negative skew to the data. The variation in the data is relatively large/ small .

A brewery needs to purchase glass bottles that can
withstand an internal pressure of at least 150 pounds per square
inch (psi). A prospective bottle vendor claims its production
process yields bottles with a mean strength of 157 psi and a
standard deviation of 3 psi.
a. Assume that the strength of the
vendor’s bottles is normally distributed. Calculate the probability
that a single bottle chosen randomly from this vendor’s factory
would fail to meet the brewer’s standard, assuming the...
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:...

Southern Glass manufactures glass bottles for a variety of
products, including perfume bottles and liquor bottles. The company
has two profit centers: production and labeling. The production
department melts the raw materials, adding metal oxides to produce
different colors if desired. It then uses a continuous rolling
process to shape the bottles. Production then transfers the bottles
to the labeling department at an average cost of $15 ($12 variable;
$3 fixed) per case. The labeling department then paints or attaches...

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).
