Percentages in Advertising Continental Airlines ran ads claiming that lost baggage is 鈥渁n area where we鈥檝e already improved 100% in the past six months.鈥� What is wrong with this statement?

Short Answer

Expert verified

An improvement of 100% is not possible in the past six months.

Step by step solution

01

Given information

The airline ad claims that there is 100% improvement in the past six months in the area of lost baggage.

02

Making percentage Interpretation of percentage

X percent value means that if a set assumed as 100 is divided into hundred equal parts, then x parts are equivalent to x%.

03

Identifying the wrong element in the stated claim

An improvement of 100% since the last six months in lost baggage implies that the number of baggage lost after this period is zero.

This condition is not possible.

Further, if 100% improvement is made in the past six months, there is no scope of improvement in this area after that period, which is also not possible.

Thus, the claim in the advertisement is wrong.

a.What is the exact value that is 73% of the 347 survey subjects?

b. Could the result from part (a) be the actual number of survey subjects who said that their companies conduct criminal background checks on all job applicants? Why or why not?

c. What is the actual number of survey subjects who said that their company conducts criminal background checks on all job applicants?

The entries are white blood cell counts (1000 cells,ML) and red blood cell counts (million cells,ML) from male subjects examined as part of a large health study conducted by the National Center for Health Statistics. The data are matched, so that the first subject has a white blood cell count of 8.7 and a red blood cell count of 4.91, and so on.

Conclusion: If we analyze the sample data and conclude that there is a correlation between white blood cell counts and red blood cell counts, does it follow that higher white blood cell counts are the cause of higher red blood cell counts?
