laptop computers Lifespans lies between what two numbers? Low: y
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
c. The middle 40% of laptop computers Lifespans lies between what two numbers?
Low: years
High: years
![### Understanding Laptop Lifespan Distribution
**Overview:**
Laptop computers, on average, have a lifespan of 14 years with a standard deviation of 2.3 years. The lifespan of laptop computers follows a normal distribution. Let the random variable \( X \) represent the lifespan of a randomly selected laptop computer. Round all answers to four decimal places where possible.
**Questions:**
a. **What is the distribution of \( X \)?**
\( X \sim N(\, \_\_\_\_ \, , \, \_\_\_\_ \,) \)
b. **Find the probability that a laptop computer’s lifespan is between 13.1 and 15.6 years.**
\(\_\_\_\_\_\)
c. **The middle 40% of laptop computers’ lifespans lie between what two numbers?**
- **Low:** \(\_\_\_\_\_\) years
- **High:** \(\_\_\_\_\_\) years
This exercise involves calculating probabilities and understanding intervals in a normal distribution, a fundamental concept in statistics.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4506b8da-c2cc-42a3-8039-41217f182aab%2F625f21b2-7e0a-46de-8feb-c907851656ff%2Fj6j57e5_processed.jpeg&w=3840&q=75)
