7x+14=6x+30
Move x into one side and whole numbers to the other.
Solve like linear equation.
7x+14=6x+30
7x-6x=30-14
x=16

Answer:
a) (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
Step-by-step explanation:
Given that:
For male students: number of male students () = 69, number who liked the new method (x) = 38
For female students: number of female students () = 73, number who liked the new method (x) = 20
a) The probability that a male student like the new method () is given as:
The probability that a female student like the new method () is given as:
c = 95%, α = 1 -c = 0.05
the difference between the proportions of male and female students who like the new method better = ± = ± = (0.124, 0.435)
b) I am 95% confident that the proportion difference is between 0.124 and 0.435
5/9.....real number....rational number
? Can u post a picture of how the question is written cause I’m kind of confused at the moment
