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, 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...
