initiative is between (round to 3 decimal places) and (round to 3 decimal places). b. If many groups of 579 randomly selected Texans and 546 randomly selected New Yorkers were surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of the difference in the proportions of Texans and New Yorkers who favor a new Green initiative and about percent will not contain the true population difference in proportions.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

![A newsgroup is interested in constructing a 95% confidence
interval for the difference in the proportions of Texans and
New Yorkers who favor a new Green initiative. Of the 579
randomly selected Texans surveyed, 408 were in favor of
the initiative and of the 546 randomly selected New
Yorkers surveyed, 450 were in favor of the initiative.
a. With 95% confidence the difference in the proportions
of Texans and New Yorkers who favor a new Green
initiative is between
(round to 3 decimal places)
and
(round to 3 decimal places).
b. If many groups of 579 randomly selected Texans and 546
randomly selected New Yorkers were surveyed, then a
different confidence interval would be produced from each
group. About
percent of these confidence
intervals will contain the true population proportion of the
difference in the proportions of Texans and New Yorkers
who favor a new Green initiative and about
percent will not contain the true population difference in
proportions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F838d694f-95c8-423d-b19c-da1557c58588%2F2558c755-9259-4b0b-a95e-510973cd715b%2Fknltfn_processed.jpeg&w=3840&q=75)
