Answer:
Confidence interval @ 90% = [0.5324 < p < 0.5656]
Step-by-step explanation:
We are given the following information:
Sample size (n) = 2430
Proportion of win (p) = 0.549
Proportion of loss (q) => 1-p = 0.451
By formula of confidence interval,
CI = p ± Z(90%) * ,
CI = 0.549±(1.645* ((0.549*(0.451))/2430))^(0.5)
CI = [0.5324 < p < 0.5656]
