Question
Transcribed Image Text:According to a recent census, 14.3% of all housing units in a
certain country are vacant. A county supervisor wonders if her
county is different from this. She randomly selects 893 housing
units in her county and finds that 162 of the housing units are
vacant. Complete parts a through d below.
a) State the hypotheses.
Let the proportion of housing units in the county that are vacant
be denoted by p. Choose the correct answer below.
OA. Ho: p<0.143
HA: P = 0.143
O C. Ho: p=0.143
HA: P<0.143
OB. Ho: p=0.143
HA: P = 0.143
O D. Ho: p20.143
HA: P<0.143
b) Name the model and check appropriate conditions for a
hypothesis test.
What kind of test is this? Choose the correct answer below.
Two-proportion t-test
Difference in proportions test
Proportional t-test
O One-proportion z-test
Check the appropriate conditions for a hypothesis test. Select
the correct choice below and fill in the answer boxes within your
choice.

OA. The 893 housing units were a random sample from the
county of interest. 893 is likely less than 10% of all
housing units in the county. One expects npo =

A. Because the P-value is so high, there is not sufficient
evidence that the proportion of housing units that are
vacant in this county differs from that in the country as a
whole.
OB. Because the P-value is so low, there is not sufficient
evidence that the proportion of housing units that are
