Answer:
Whers the pic
Step-by-step explanation:
The result of taking the difference between sample means, minus the null hypothesized difference, divided by the standard error of the difference between means is the t-statistic.
<h3>What is a t-statistic?</h3>
When deciding whether to accept or reject the null hypothesis in a T test, the t-statistic is used. It functions similarly to a Z-score in that you choose a cutoff point, calculate your t score, and then compare the two. When you have a limited sample size or don't know the population standard deviation, you utilize the t-statistic.
On its own, the t-statistic doesn't actually reveal much. Similar to how the word "average" is meaningless on its own without any context.

Answer:
You would click (1,-5)
Step-by-step explanation:
The absolute minimum is the lowest point of the graph.
In all graphs, if it says minimum, it almost certainly means that lowest point, and if there are more than one, you would simply click on those.
It does not matter how many points there are, only that they are the lowest.
Therefore, it would be 1,-5.
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
