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 fin- their ages from local records. The accompanying table shows the data for each sample (in years). Complete parts a through e below. <:> a) Find the sample means for each neighborhood. 371 = D years 92 = D years (Type integers or decimals.) Data table b) Find the estimated difference ofthe mean ages of the two neighborhoods, {/1 - {(2. The estimated difference is D years. :I (Type an integer or a decimal.) Neighborhood c) Find the sample variances for each neighborhood. 1 sea am (Type integers or decimals.) Neighborhood 2 d) Find the sample standard deviations for each neighborhood. (Round to two decimal places as needed.) e) Find the standard error of the difference of the two sample means. SF (91 :92) = DEF\
