Select all statements that are true about electric potential (voltage). Group of answer choices it's a vector it depends on the
source and not a subject or test charge it can be positive, negative, or zero only changes in the electric potential are physically meaningful it is equal to the electric potential energy a conductor in electrostatic equilibrium has the same voltage throughout the interior and surface it always increases as you move away from any charged object
1 answer:
Answer:
See explaination
Explanation:
a) The alternate hypothesis for the study is:
H1: There is a significant difference between mean grade of male and female students.
b) The null hypothesis is:
H0: There is no significant difference between mean grade of male and female students.
c) The Level of Significance is 0.05
d) The computed t critical value for the study is 0.632
e) The P-value of the test is 0.531
f) Conclusion: The p-value of t test is greater than 0.05. Hence we accept null hypothesis at 5% level of significance and conclude that there is no significant difference between mean grade of male and female students
