In Exercises 1-4, write the negation of the statement.
1. All Acuras are Hondas.
To write: The negation of the statement “All Acuras are Hondas”.
Answer to Problem 1RE
The negation of the statement “All Acuras are Hondas” is “Some Acuras are not Hondas”.
Explanation of Solution
Result used:
A statement which gives the exact opposite meaning of the given statement is called its negation
The negation of quantified statements is summarized as follows.
Form of statement | Form of negation |
All are | Some are not |
None are | Some are |
Some are | None are |
Some are not | All are |
Calculation:
The given statement is “All Acuras are Hondas”.
Using the above table from the result, the negation of “All are” is “Some are not”.
That is, “All Acuras are Hondas” can be written as “Some Acuras are not Hondas”.
Therefore, the negation of the given statement is “Some Acuras are not Hondas”.

- A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 319 people over the age of 55, 65 dream in black and white, and among 296 people under the age of 25, 19 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25.
