Answer:
Option C
Step-by-step explanation:
From the picture attached,
Given:
SE ≅ EP
∠ESA ≅ ∠ EPN
To Prove:
ΔSEA ≅ ΔPEN
Solution:
Statements Reasons
1). SE ≅ EP 1). Given
2). ∠ESA ≅ ∠ EPN 2). Given
3). ∠SEA ≅ ∠NEP 3). Vertical angles theorem
4). ΔSEA ≅ ΔPEN 4). By ASA postulate
Therefore, Option C is the correct option.
A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative, I hope this helps

Answer:
B. Goodness-of-Fit Test
Step-by-step explanation:
Given that a professor expects that the grades on a recent exam are normally distributed with a mean of 80 and a standard deviation of 10.
She records the actual distribution of grades and wants to compare it to the normal distribution
For this expected values are to be got assuming normal and the observed and expected are used to calculate chi square.
Depending on the chi square statistic conclusion is made
Here the test to be done is
B) Goodness of fit test.
A is wrong because test of independence is done when there are more than one categorical variable in the rows.
C is wrong because here homogeneity is not tested
Only B is right.
