The random sample of the students is an illustration of sampling
The chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.
<h3>How to determine the reason chi square is not appropriate?</h3>
The dataset is given as:
Monday 34
Tuesday 29
Wednesday 32
Thursday 28
Friday 19
The variable of the above dataset is a not a categorical dataset.
One of the conditions of the chi-square test for goodness of fit test is that the variable under study must be categorical.
Hence, the chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.

7. (1,2),(0,-1)
slope = (-1 - 2) / (0 - 1) = -3/-1 = 3 <==
8. (-1,0),(1,-1)
slope = (-1 - 0) / (1 - (-1) = -1 / 2 <==
Answer:
P(A n B) = 0
Step-by-step explanation:
Given
Traces of TNT detected
No traces of TNT
Required
Probability of false positive
From the question, we understand that A and B must occur to get a positive and the result is 0.
The probability of A and B is represented as: P(A n B)
Include the result (0), we get:
P(A n B) = 0
