i hope this helped. if i did it wrong i apologize.
11/18 is simplified as a mixed number it would be 0 11/18
Construct a 99% confidence interval for life
expectancy of a new GE light bulb:<span>
n = 64
Xbar = 750
s.d. = 20
Critical z value at 99% confidence = 2.576
margin of Error, E = 2.576*20/√64 = 6.44
<span>99% confidence interval for life expectancy of a
new GE light bulb = (Xbar - E; Xbar + E) = (743.56; 756.44)</span></span>
