The t-test is commonly used to examine whether exactly two groups are significantly different from each other on some score or measure.
The t-test is a a type of inferential statistic used to compare the means of two groups. This is often used in hypothesis testing to determine if a process really affects the population of interest, or if the two groups are different from each other. The t-test shows how important the difference between group means is. It notifies you if these differences may have occurred by mistake. Companies use the t-test to compare two different means and see if they come from the exact same population.

Answer:
United States v. Windsor legalized same-sex marriage in the United States.
Explanation:
Although the United States v. Windsor case in 2013, represents a landmark on civil rights, that set the focus on civil rights for married same-sex couples, and set a precedent for the later legalization of these unions, it did not legalize same-sex marriage in the United States.
It was the Obergefell v. Hodges case, in 2015, in which the Supreme Court ruled that the right to marry was a fundamental right that should be guaranteed for same sex couples, requiring all fifty states to perform and recognize same-sex marriage.

Summarizing is important because it makes the information easier to understand. for example, let’s say the topic was why we invaded sicily during wwii. i could go into great detail about each of the operations and what their purpose was, going way back in history to find a bunch or causes, picking through every decision made at every level of the army or i could summarize and say we invaded sicily since we weren’t ready to invade germany, and we diverted german troops from russia. what could have been a whole paragraph on the subject was just narrowed down to a sentence. hope that helps :D
