When 490 college students were surveyed, 130 said they own their car. Construct a 95%
confidence interval for the proportion of college students who say they own their cars.

Answers

Answer 1

Answer:

0.2454 ≤ x ≤ 0.2852

Explanation:

Given the following parameters:

Number of students = 410

Number of students that own their cars = 130

Hence we have Proportion of those who own a car (P) = 130/490 = 0.2653

Thereby, at 95% confidence, Z = 1.96

Sample size is represented as N = 490

Confidence interval = P+/- Z * Sqrt (P (1-P) / N)

=> 0.2653 +/- 1.96 * Sqrt (0.265 (1-0.265) / 490)

=> 0.2653 +/- 0.0199

Therefore, for any randomly selected student (y), the probability that he/she owns a car is;

0.2454 ≤ x ≤ 0.2852

The most important purpose of government as detailed in the Preamble to the U.S. Constitution is:

To establish justice.

Explanation:

The other purposes of government are secondary to the establishment of justice.  The enthronement of justice ensures the realization of the other purposes.  Without justice, the government will not be able to achieve any domestic tranquility.  Without justice, the government will not be able to realize the common defense of all.  Without justice, the government cannot promote the general welfare of the citizenry.  Without justice, the government cannot secure the blessings of liberty.  Therefore, justice is the fulcrum for the sustenance of the existence of every government.  Otherwise, the government simply becomes a pack of cards, without meaning and order.

Monthly Medicare (1.45%): $?
Monthly State Tax (4%): $?
Monthly Local Tax (0.1%): $?
Total Monthly deductions $?
Trey’s NMI $?

Answers

Answer:

Gross monthly income:$1,125

Monthly Federal income tax (11.6%): $130.50

Monthly Social security (FICA) (6.2%): $69.75

Monthly Medicare (1.45%): $16.3125

Monthly State Tax (4%): $45

Monthly Local Tax (0.1%): $1.125

Total Monthly deductions $262.6875

Trey’s NMI $862.3125

Explanation:

Calculation for What is his monthly taxes

First step is to calculate the Gross monthly income

Using this formula

Gross monthly income=Annual salary/Numbers of months in a year

Let plug in the formula

Gross monthly income=$13,500/12 months

Gross monthly income=$1,125

Therefore the Gross monthly income is :$1,125

Monthly Federal income tax (11.6%): $130.50

($1,125*11.6%)

Monthly Social security (FICA) (6.2%): $69.75

($1,125*6.2%)

Monthly Medicare (1.45%): $16.3125

($1,125*1.45%)

Monthly State Tax (4%): $45

($1,125*4%)

Monthly Local Tax (0.1%): $1.125

($1,125*0.1%)

Total Monthly deductions $262.6875

($130.50+$69.75+$16.3125+$45+$1.125)

Trey’s NMI $862.3125

Trey’s NMI=Gross monthly income-Total Monthly deductions

Trey’s NMI=$1,125-$262.6875

Trey’s NMI=$862.3125

Therefore his monthly taxes are:

Gross monthly income:$1,125

Monthly Federal income tax (11.6%): $130.50

Monthly Social security (FICA) (6.2%): $69.75

Monthly Medicare (1.45%): $16.3125

Monthly State Tax (4%): $45

Monthly Local Tax (0.1%): $1.125

Total Monthly deductions $262.6875

Trey’s NMI $862.3125

Answers

Answer: Nations of Latin America won independence

Explanation:

As Creoles and Mestizos became discontented with Spanish rule, they began to demand more self-governance from the Spanish which would eventually boil over to them asking for independence.

This was made easier when Napoleon invaded Spain during the Napoleonic wars and severely weakened Spain's power to hold onto its colonies. Revolutions in North America such as the American Revolution spurred some colonies to seek independence such as Haiti from France which went through its own Revolution as well.

These three factors allowed nations in Latin America to seek their independence and led to many getting it.
