In a random sample of eleven people, the mean driving distance to work was 24.7 miles and the standard deviation was 5.5 miles. Assume the population is normally distributed and use the t-distribution to find the margin of error and construct a 95% confidence interval for the population mean µ. Interpret the results. Identify the margin of error. (Rou } as needed.) Con miles per hour interval for the population mean. square miles (Rou miles e as needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.)
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.

(Type an integer or a decimal. Do not round.)
O A. It can be said that
% of the population has a driving distance to work (in miles) that is between the interval's endpoints.
O B. With
% confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints.
OC.
% of all random samples of eleven people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints.
O D. With
% confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdac0d91e-d556-4f35-997e-fb34efe7a339%2F3c14e51f-01df-4551-ae56-599a9bc72631%2Fw5gbjzf_processed.jpeg&w=3840&q=75)
