Answer:
(0.5455 ; 0.7545)
Step-by-step explanation:
Given that:
Sample size, n = 80
Baseball fans, x = 52
Proportion, p = x/n = 52 / 80 = 0.65
Using the relation :
Confidence interval :
p ± Zcrit√[(p(1 -p))/n]
Zcrit at 95% = 1.96
Lower boundary: p - Zcrit√[(p(1 -p))/n]
0.65 - 1.96√[(0.65(1 -0.65))/80]
0.65 - 1.96√[(0.65(0.35))/80]
0.65 - 1.96 * √0.00284375
0.65 - (1.96 * 0.0533268)
0.65 - 0.104520528
= 0.545479472
Upper boundary: p + Zcrit√[(p(1 -p))/n]
0.65 + 1.96√[(0.65(1 -0.65))/80]
0.65 + 1.96√[(0.65(0.35))/80]
0.65 + 1.96 * √0.00284375
0.65 + (1.96 * 0.0533268)
0.65 + 0.104520528
= 0.754520528
(0.5455 ; 0.7545)
