Transcribed Image Text:In 2010, the Maricopa Community College District's enrollment data
showed the following breakdown of students by ethnicity: 54.9%
White; 21.1% Hispanic; 7.9% Black; 4.5% Asian/Pacific Islander;
2.9% Native American; 8.7% Other. Information was collected from
a random sample Of 300 students in 2017 to determine whether or
not the data has changed significantly. The sample data is given in
the table below. At the a = 0.05 level of significance, test the claim
that the ethnic breakdown of students at MCCCD has not changed
significantly since 2010.
Which would be correct hypotheses for this test?
| Ho: The breakdown of students by ethnicity has not changed
significantly since 2010 (i.e. the given distribution still fits); H :
The breakdown of students by ethnicity has changed
significantly since 2010 (i.e. the given distribution no longer
fits)
Ho:H1 = H2; H1:µ1 # 42
| Ho:P1 = P2; H1 :P1 # P2
) Ho: The breakdown of students by ethnicity has changed
significantly since 2010 (i.e. the given distribution no longer
fits); H: The breakdwon of students by ethnicity has not
changed significantly since 2010 (i.e. the given distribution still
fits)
