Answer:
y = 5
Step-by-step explanation:
AB = | 8 - (- 4) | = | 12 |= 12
Divide 12 by the sum of the parts of the ratio, 1 + 3 = 4
12 ÷ 4 = 3
Thus
y = 8 - 3 = 5
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]
