To find:
The value of the given table represents a linear or an exponential function.

Answer to Problem 33E
This is exponential
Explanation of Solution
Given:
Each entry in a two −way table
Concept used:
Bivariate joint frequency distribution are
The total row and total column of the marginal distribution while the body of the table is the joint frequencies
Calculation:
The total row and total column of the marginal distribution while the body of the table is the joint frequencies
Each entry in a two-way table is called a joint frequency
The data collected from one source belong to two different categories.
x | 0 | 1 | 2 | 3 | 4 |
y | 144 | 24 | 4 | 23 | 19 |
The first difference are 120,−20,−103,−59
This is not constant so it is not linear.
The second difference are 100,503,259
This is not constant so it is not quadratic
The function has a common ratio 16
So, this is exponential.

- 1. Differentiate between discrete and continuous random variables, providing examples for each type. 2. Consider a discrete random variable representing the number of patients visiting a clinic each day. The probabilities for the number of visits are as follows: 0 visits: P(0) = 0.2 1 visit: P(1) = 0.3 2 visits: P(2) = 0.5 Using this information, calculate the expected value (mean) of the number of patient visits per day. Show all your workings clearly.
