Answer:People have made art for thousands of years. Some of the earliest art comes from the Stone Age, a time period during which early humans first made and used simple stone tools. Scholars divide the Stone Age into three spans of time: the Paleolithic (the word literally means old stone age), which runs from 2,500,000 to 10,000 BC; the Mesolithic, from 10,000 - 4000 BC; and the Neolithic, from 4000 - 2000 BC. In each period, the tools became a little more complex. The art from this time is also sometimes also called prehistoric art, because it was made before recorded history.
The people who created Stone Age art relied on natural materials they found in their environment. They used all types of stone and also mammoth ivory, animal bones and antler out of which they carved small figurines. They painted on cave walls, using clay ochres and iron oxide for yellows and reds, and manganese oxide and charcoal (burnt wood) for black. Think of the first ancient painters. How did they figure out what substances left the best mark? Stone Age art is an interesting glimpse into the ingenuity of early humans.
Explanation:
It really depends on how you look at after the fight with Germany ended we were still fighting Japan but the U.S dropped 2 atomic bombs killing over 360,000 people they did it without telling the allies because they wanted to send a message to Russia basically saying that we have these types of weapons don’t mess with us basically a flex. After the bombs were dropped the war ended but I don’t believe justice was served because the U.S committed a war crime by dropping those bombs and they did it for research purposes because as soon as the war ended they sent over researchers to go collect data on what happened and how it effected the people. There is a lot more in depth stuff that will make my argument more strong but if I type all that out I will be here all day. Over all I don’t believe justice was served but that’s everyone’s own opinion.

Answer:
HI your question is incomplete attached to the answer is an image of the complete question
i) MSG
II) OVER
III) MSE
IV) UNBIASED
Explanation:
MSG ( ) : this is calculated by taking the sample variance of the sample distribution of the mean for every group involved with the test and it unbiased under the null hypothesis alone
while MSE is gotten from using the sample mean of the sample variances of each group involved with the test and it is always unbiased whether or not there is a population / treatment effect
