How does 0.4 - 0.453 = 0.247 and how does 0.4 + 0.453 = 0.553?

(f)
The 95%. confidence interval for I
>_MCE I 1.96 √ (var(x))
Subsitute the
var(x)
MLE
=0.0533
value XMLE
= 0.4 and
X_MLE ± 1.96 √0.0533
AMLE I 1.96 x 0.2308
95%. Confidence level for x = (0.4-0.453, 0-4 +0.453)
so,
The 95%. confidence interval for is approximately
(0.247, 0.553).
