(d) Suppose you obtain a simple random sample of size n= 10 of a specific type of mini-vehicle that was in a low-impact collision and determine the cost of repair. Do you think a95% confidence interval would be wider or narrower? Explain.O A. Narrower, because there is less variability in the data because any variability caused by the different types of vehicles has been removed.OB. Wider, because there is more variability in the data because variability in the repair cost of the car has been added.OC. Wider, because taking a second random sample will always lead to a wider confidence interval.OD. Narrower, because taking a second random sample will always lead to a narrower confidence interval.

Concept explainers

Percentage

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

(d) Suppose you obtain a simple random sample of size n= 10 of a specific type of mini-vehicle that was in a low-impact collision and determine the cost of repair. Do you think a
95% confidence interval would be wider or narrower? Explain.
O A. Narrower, because there is less variability in the data because any variability caused by the different types of vehicles has been removed.
OB. Wider, because there is more variability in the data because variability in the repair cost of the car has been added.
OC. Wider, because taking a second random sample will always lead to a wider confidence interval.
OD. Narrower, because taking a second random sample will always lead to a narrower confidence interval.
