Answer: 0.84
Step-by-step explanation:
let p be the population proportion of adults who smoked a cigarette in the past week.
As per given , we have

Sample size : n= 1491
The sample proportion of adults smoked a cigarette= 
The test statistic for proportion is given by :-

Substitute all the values , we get

Hence, the value of the test statistic = 0.84
You answer would be B. Vehicle B needs fewer repairs then Vehicle A on average and its repair rate is more consistant
Let C represent the temperature in Celsius, and let F represent the temperature in Fahrenheit.
F=1.8C+32
Using that equation, plug in the numbers. F=1.8*25+32. F=77
Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X
