Answer:
The standard deviation of the sample mean is 16.98.
Explanation:
The standard deviation of the sample mean differences is given as by the difference of the 2 standard deviations.This is given as
Difference of standard deviations=21.2-17.6 = 3.6
Now the ratio of the difference to the largest standard difference is given as
Ratio=3.6/21.2=0.1698
Converting this into percentage as 0.1698x100=16.98
The standard deviation of the sample mean is 16.98.
The two events occurred in Boston that caused tension between British Parliament and the colonists were the Boston Massacre of 1770 and the Boston Tea Party of 1773.
-The Boston Massacre took place on the night of March 5, 1770. The tension caused by the military occupation of Boston, increased after the firings that a group of soldiers made against a group of protesters protesting against the rate hike on the part of England to recover from the economic losses after the war. John Adams would later say that, after the night of the Boston Massacre, the desire for independence of the United States of America began.
-The 16 of December of 1773 took place in Boston the denominated Boston Tea Party, in which a shipment of tea was sent to the sea. A group of settlers disguised as Indians threw the cargo of tea from three British ships into the sea. It was an act of protest by the American colonists against Great Britain and is considered a precedent of the United States War of Independence.
The rebellion of the settlers in the port of Boston was born as a result of the approval by Great Britain in 1773 of the Tea Act, which taxed the import from the metropolis of various products, including tea, to benefit the British Company of the East Indies to whom the colonists boycotted buying the tea of the Netherlands.
