Transcribed Image Text:According to a recent census, 15% of the people in the United States are of Hispanic origin. One county supervisor believes her county has a different proportion of Hispanic
people than the nation as a whole. She looks at their most recent survey data, which was a random sample of 457 county residents, and found that 48 of those surveyed are
of Hispanic origin. Complete parts (a) through (d) below.
(The proportion of people in the county that are of Hispanic origin is denoted by p.)
A. Ho: p = 0.15
HA: P<0.15
C. Ho: p=0.15
HA: P 0.15
b) Name the model and check appropriate conditions for a hypothesis test.
What kind of test is this?
One-proportion z test
Difference in differences test
Two-proportion t test
Proportional t test
