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 accompanying table shows the data for each sample (in years). Complete parts a through e below. Click the icon to view the data table. a) Find the sample means for each neighborhood. y1 = 54 years y2 = 43 years (Type integers or decimals.) b) Find the estimated difference of the mean ages of the two neighborhoods, y1 - y2. The estimated difference is 11 years. (Type an integer or a decimal.) c) Find the sample variances for each neighborhood. S = 62 S? = 68.4 (Type integers or decimals.) d) Find the sample standard deviations for each neighborhood. $1 = 7.87 years $2 = 8.27 years (Round to two decimal places as needed.) e) Find the standard error of the difference of the two sample means. SE (y1 - y2) = 4.66 years Round to two decimal places as needed.)X Data table Neighborhood 1 Neighborhood 2 45 48 67 34 46 35 47 40 53 55 54 58 Print Done
