A road traffic safety research study examined winter tire use in the passenger cars in two nearby cities. Number of the cars examined in city 1 are 100 (n1 ) and 60 of the cars have winter tires. On the other hand, in the city 2,120 (n2 ) passenger cars are examined and 78 of the cars have winter tires. What is the alternate hypothesis?

H1 : p1 = p2 |
|
H1 : p1 ≠ p2 |
|
H1 : p1 < p2 |
|
H1 : p1 > p2 |
|
H0 : p1 = p2 |
Yanıt Açıklaması:
In this question, the parameter of interest is the winter tire use proportion in the passenger cars in two nearby cities. The group sizes for the city 1, n1 = 100 and for the city 2, n2 = 120. Then, hypothesis can be expressed as follows: H0 : p1 = p2 H1 : p1 ≠ p2. Therefore, the correct answer is B.
