Question
Let population 1 be drivers of age
25-34
and let population 2 be drivers of age
50-59. An insurance company collects data on​ seat-belt use among drivers in a country. Of
1900
drivers
25-34
years​ old,
19​%
said that they buckle​ up, whereas
487
of
1800
drivers
50-59
years old said that they did. At the
10​%
significance​ level, do the data suggest that there is a difference in​ seat-belt use between drivers
25-34
years old and those 
Use the​ two-proportions z-test to conduct the required hypothesis test. What are the hypotheses for this​ test?
 
 
A.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 greater than p 2
H0: p1=p2, Ha: p1>p2
 
B.Upper H 0 : p 1 not equals p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1≠p2, Ha: p1=p2
 
C.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 not equals p 2
H0: p1=p2, Ha: p1≠p2
Your answer is correct.
 
D.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 less than p 2
H0: p1=p2, Ha: p1<p2
 
E.Upper H 0 : p 1 less than p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1<p2, Ha: p1=p2
 
F.Upper H 0 : p 1 greater than p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1>p2, Ha: p1=p2
Part 2
Calculate the test statistic.
 
z=negative
​(Round to two decimal places as​ needed.)
Part 3
Calculate the​ P-value.
 
P=0.2890.289
​(Round to three decimal places as​ needed.)
Part 4
Which of the following is the correct conclusion for the hypothesis​ test?
 
 
A.
At the
5​%
significance​ level,
reject
H0​;
the data
provide
sufficient evidence to accept
Ha.
 
B.
At the
5​%
significance​ level,
reject
H0​;
the data
do not provide
sufficient evidence to accept
Ha.
Your answer is not correct.
 
C.
At the
5​%
significance​ level,
do not reject
H0​;
the data
do not provide
sufficient evidence to accept
Ha.
This is the correct answer.
 
D. At the 5​% significance​ level, do not reject
H0​; the data
provide
sufficient evidence to accept
Ha.
