Answer)
E = z*√{p*(1-p}/√n
√n = z*√{p*(1-p)}/E
Given z = 1.95996
P = 0.62
E = 0.05
We need to find sample size n
After substitution
N = 363
4)
Margin of error = z*√{p*(1-p)}/√n
Z = 1.95996
P = 0.72
N = 300
After substitution
Answer is = 0.05080797015 = 0.05
Excel function for margin of error is
NORM.S.INV(1 – α/2) * SQRT[ (p_bar * q_bar) / n]

Directions: Show all work including steps used during computations using formulas and diagrams when appropriate. Write a DETAILED statement explaining the meaning of your computations (conclusions) for all problems- hypothesis tests and confidence intervals. Remember that the conclusions for hypothesis tests need both a statement about the null and alternative hypotheses and another sentence or two describing how that applies specifically to the context given in the question. EXTRA CREDIT: You intend to poll students in order to determine the...
