Bottom right is the correct answer
The random sample proportion:
at 90% confidence interval: The Central 90% of any normal distribution is: Z_(α/2) = 1.960
Error = E = ±5% = ±0.05
Applying the normal distribution theory,
= 0.70 ≤ P≤ 0.77(this means that we are 90% confident that the true proportion of jet with wiring problem fall with 0.70 and 0.77, hence there is no need for the airline to conduct further sampling, rather, they should just inspect all the planes)

The right expression is -1-2/7-(-3) which then gives you -3/10
Step-by-step explanation:
The picture is in sphere shape
so if you move it will be in the same position
