Sample size, n = 75
Point estimate, p = 52/75 = 0.693
Z at 99.7% confidence interval ≈ 2.96
Population mean interval = p+/- Z*Sqrt [p(1-p)/n]
Substituting;
Population mean interval = 0.693 +/- 2.96*Sqrt [0.693(1-0.693)/75] = 0.693+/-0.158 = (0.535,0.851) or (53.5%,85.1%)
Step-by-step explanation:
5x2-40
5(x2-8)
i hope it helps
The answer is 40% and 0.4
I don’t understand very much your question can you take it again so I could help
Solve the equation and it will add up to -6 so
3×-7=-21
-21-10=-31
-31+25=-6
