Answer:
(0.089 ; 0.151)
Step-by-step explanation:
Given :
Sample size, n = 300
Number of defective items, x = 36
The confidence interval required here is that for a one sample proportion :
The confidence interval is defined thus :
Phat ± Zcritical * √[Phat(1 - phat) / n]
Zcritical at 90% = 1.645
Phat = x / n = 36 / 300 = 0.12
Hence,
C.I = 0.12 ± 1.645 * √[0.12(1 - 0.12) / 300]
C.I = 0.12 ± (1.645 * 0.0187616)
C.I = 0.12 ± 0.0308629
C.I = (0.089 ; 0.151)
Answer:
it's either B or D but you would have to do the math
Step-by-step explanation:
Answer:
A. 30Lbs. 6 oz.
B. 27Lbs. 4oz.
Step-by-step explanation:
Considering that there are 16 ounces in one pound, you just have to add the ounces first so, 9+ 13= 22, subract that with 16 to get 6 ounces and carry the 16 ounces to 1 pound,the add the pounds. Now do that with the second equation.
8+12= 20
20-16= 4
15+11=26+1= 27
27 pounds and 4 ounces
30 pounds and 6 ounces
Answer:
Add five to both sides
Step-by-step explanation:
X= a +5
