Answer:
Number of students ; 60
Explanation:
Using the formula for p +- z * Sqrt ( pq/n )
Let us first calculate the Margin of Error
= 0.816 –0.7 = 0.116
•z* = 1.96
P = (0.584 + 0.116 ) = 0.7
Q = 1- p = 1 – 0.7 = 0.3
Now inserting the values in the formula; we get
0.116 = 1.96 x sqrt { ( 0.7 x 0.3) / n }
Solving the above equation
N = 60 (rounded off to nearest number)
Hence the number of students that were selected by the environmental teacher in the sample is 60
- The origins of slavery in Britain's North American colonies can be traced back to the early 1600s, when the first African slaves were brought to the Virginia colony. At first, these slaves were used primarily for labor in the tobacco fields. However, by the mid-1700s, the use of slaves had spread to other areas of the colonies, such as the Carolinas and Georgia, where they were used for labor in the rice and indigo fields.
- The development of slavery in the British colonies was largely shaped by the demand for labor. As the colonies grew and became more economically prosperous, the demand for labor increased. This led to the importation of more slaves from Africa. By the time of the American Revolution, there were an estimated 500,000 slaves in the British colonies.
North American colonies:
The British North American colonies were well-established communities that were tightly linked to the Atlantic and Caribbean commerce networks. Although religious ideals drove many settlers, others regarded the colonies as a chance to buy their own land, work for themselves, or strike it rich.
