True or False:
Suppose the Chi-Square test for independence is being used to test if two variables, erratic driving and cell phone usage, are statistically independent. A proper way to express the null and alternative hypotheses is as follows:
H0: Erratic driving and cell phone usage are independent
Ha: Erratic driving and cell phone usage are not independent

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
