Answer: The correct option are 1 and 4 .
Explanation:
It is given that 
, it means AB = LM, BC=MN, AC=LM, 
, \angle B=\angle M and \angle C=\angle N as shown in the figure.
All the possible way to write is given below,
So, the correct options are 1 and 4.
According to the second
, it means 
and 
which is not exactly true, therefore it is not a correct option.
According to the second
, it means and which is not exactly true, therefore it is not a correct option.
Not sure if this is a full equation. The first equation I got -2.833. The second equation I got 3.250
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.
