Soil engineers hypothesize that the share of limestone in Austin’s soils is the same as that in San Antonio soils. They take 100 bore holes in each region, with 70 showing limestone in Austin and 60 showing limestone in San Antonio. Assuming a test significance level of =0.05, will you accept their hypothesis?
