Answer:
0.12 ± 1.96 * √(0.12(0.88) / 100)
Step-by-step explanation:
Confidence interval :
Phat ± Zcritical * √(phat(1 -phat) / n)
Phat = 12/100 = 0.12
1 - phat = 0.88
Zcritical at 95% = 1.96
Hence, we have :
0.12 ± 1.96 * √(0.12(0.88) / 100)
0.12 ± 1.96 * 0.0324961
0.12 ± 0.0636924
Lower boundary = (0.12 - 0.0636924) = 0.0563
Upper boundary = 0.12 + 0.0636924 = 0.1837

=28
60÷8= 7 remainder 4
86÷6= 14 remainder 2
15÷6= 2 remainder 3
56÷2= 28
If you're diving by decimals then...
60÷8= 7.5
86÷6= 14.3 Draw a line over the number like this ___
14.3
15÷6=2.5
56÷2= 28.0 or 28.
Hope this helps!!
