Question

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

Answer 1

See explaination

Step-by-step 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
