Hello!
The parameter of interest is "the population proportion of people that like soccer A news channel"= p
The hypothesis are:
H₀: p = 0.45
H₁: p ≠ 0.45
To study the population proportion you have to use the approximation of the standard normal distribution:
≈ N(0;1)
A sample of n=30 was taken and surveyed, 18 of those answered positively, then the sample proportion is:
p'= 18/30= 0.6
The statistic under the null hypothesis is:

I hope it helps!
Answer:2
Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.
