A simple random sample of size nequals 200
drivers were asked if they drive a car manufactured in a certain country. Of the 200

drivers​ surveyed, 114

responded that they did. Determine if more than half of all drivers drive a car made in this country at the alpha equals 0.05

level of significance. Complete parts ​(a) through ​(d).
​(a) Determine the null and alternative hypotheses.
Upper H 0
​:




0.5

Upper H 1
​:




0.5
​(b) Calculate the​ P-value.
​P-valueequals
nothing
​(Round to three decimal places as​ needed.)
​(c) State the conclusion for the test.
Choose the correct answer below.
A.
Do not reject

Upper H 0

because the​ P-value is less than

the alpha
equals0.05

level of significance.
B.
Reject

Upper H 0

because the​ P-value is less than

the alpha
equals0.05

level of significance.
C.
Reject

Upper H 0

because the​ P-value is greater than

the alpha
equals0.05

level of significance.
D.
Do not reject

Upper H 0

because the​ P-value is greater than

the alpha
equals0.05

level of significance.
​(d) State the conclusion in context of the problem.
There


is
is not

sufficient evidence at the alpha equals 0.05

level of significance to conclude that more than half of all drivers drive a car made in this country.
