Hypothesis test results:

Difference Count1 Total1 Count2 Total2 Sample Diff. Std. Err. Z-Stat P-value
p1 - p2 9 31 8 30 0.023655914 0.1148271 0.20601333 0.8368

From the given data n1 = 31 , x1 = 9

n2 = 30 , x2 = 8

sample proportion (1) = 9/31 = 0.29

sample proportion (2) = 8/30= 0.27

since n11 = 9 > 5

n1*(1-1) = 22.01 > 5

since n22 = 8 > 5

n2*(1-2) = 21.9 > 5

so conditions are satisfied

A study is made of residents in Phoenix and its suburbs concerning the proportion of residents who subscribe to Sporting News. A random sample of n1 = 90 urban residents showed that r1 = 10 subscribed, and a random sample of n2 = 99 suburban residents showed that r2 = 18 subscribed. Does this indicate that a higher proportion of suburban residents subscribe to Sporting News? Use a 5% level of significance. What are we testing in this problem? single...
