The principal of a school surveyed 200 students on the time they spent on the Internet after school . The mean and the standard deviation of the sample data are 2.4 hours and 0.8 hours , respectively . What is the margin of error for 95 % confidence interval ?

Answers

Answer 1

Answer:

11%

Explanation:

Sample size, n = 200

Mean, m = 2.4

Standard deviation, s = 0.8

Z critical at 95% = 1.96

Margin of Error = Zcritical * sqrt(s^2 / n)

Margin of Error = 1.96 * sqrt(0.0032)

Margin of Error = 1.96 * 0.0565685

Margin of Error = 0.1108743

Hence, margin of error at 95% confidence interval is (0.1108743 * 100%) = 11.08% = 11%

Answer 2

The mean and the standard deviation of the sample data are 2.4 hours and 0.8 hours . Therefore, the margin of error for 95 % confidence interval is equal to 11%.

What is the term Margin of Error about?

A margin of error helps to provide the information about the difference between the real population value and expected results.

Given Information:

Sample size, n = 200

Mean, m = 2.4

Standard deviation, s = 0.8

Z critical at 95% = 1.96

Solution:

Margin of Error = Z critical * sqrt(s^2 / n)

Margin of Error = 1.96 * sqrt(0.0032)

Margin of Error = 1.96 * 0.0565685

Margin of Error = 0.1108743

Hence, margin of error at 95% confidence interval is (0.1108743 * 100%) = 11.08% = 11%

Answers

Answer:

the bill of rights and the gorious revolution

Explanation:

Passage of the English Bill of Rights and the Glorious Revolution indirectly influenced the American Revolution. Thus, option A and E are correct.

What was American revolution?

From 1765 and 1791, British America underwent an ideological and political change known as the American Revolution. In the American Revolutionary War (1775–1783), the Americans in the Thirteen Colonies created sovereign states that defeated the British, gaining independence from the British Crown and founding the United States as the first nation-state based on liberal democratic Enlightenment values.

The British Parliament was taxing the American colonies, but the colonists protested because they had no direct representation in that assembly. Before the 1760s, the British colonies in America maintained a significant degree of internal autonomy, with provincial legislatures in charge of local governance. But in the 1760s, the British Parliament approved a number of laws meant to bind the American colonies to British rule.

Therefore, we can conclude that option A and E are correct.
