Question:

Tickets are numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number which is a multiple of 3 or 5?

Jasjeet K.
Answer:

Here, S = {1, 2, 3, ....20} Let E = event of getting a multiple of 3 or 5 = {3, 6, 9, 12, 15, 18, 5, 10, 20} Therefore, P(E) = n(E)/n(S) = 9/20

Question:

Suppose you have a test statistic which under a certain hypothesis H0: has a chi square distribution with 12 degrees of freedom. In your data set, the test statistic is calculated to be 12. Do you reject H0 At 1% confidence interval ?

Jasjeet K.
Answer:

The relevant table of chi square distribution will be used. We will find out the value at the given degrees of freedom, and 99th percentile is what we will use. There the critical value is 26.217 , which is more than the statistic and hence you accept the null hypothesis.

The capital structure of a firm is its mix of different securities issued by that firm. It looks at the combination of short and long-term debt securities , preferred stocks and equity that will be used to finance a firm's assets.
