A developer wants to know if the houses in two different neighborhoods were built at roughly the same time. She takes a random sample of six houses from each neighborhood and finds their ages from local records. The accompanyi table shows the data for each sample (in years). Assume that the data come from a distribution that is Normally distributed. Complete parts a through c below. E Click the icon to view the data table. a) Find a 95% confidence interval for the mean difference, p, -H2, in ages of houses in the two neighborhoods. Data Table (OD (Round to two decimal places as needed.) b) Is O within the confidence interval? Neighborhood 1 Neighborhood 2 Yes 66 47 No 55 44 47 48 57 52 c) What does the confidence interval suggest about the null hypothesis that the mean difference is 0? 68 33 43 58 O A. Fail to reject Ho since 0 is a plausible value for the true mean difference. O B. Reject H, since 0 is not a plausible value for the true mean difference. Print Done O c. Fail to reject Ho since 0 is not a plausible value for the true mean difference. O D. Reject Ho since 0 is a plausible value for the true mean difference.

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.
