Answer:
Step-by-step explanation:
The probability would be "what we want" divide by "total number".
Here, <em>total amount of bread (both white and wheat) is 16 + 15 = 31</em>
Also, <em>we want probability of wheat bread. How many are there? 15</em>
<em />
<u>Thus, we divide 15 by 31.</u>
<u />
Probability (Wheat) = 15/31

Answer:
The right answer is:
(a) 0.01252
(b) 0.8882
(c) 0.9544
Step-by-step explanation:
Given:
Population proportion,
P = 0.17
Sample size,
n = 900
(a)
The standard error of proportion will be:
⇒
By putting the values, we get
(b)
We know that,
Now,
⇒
By substituting the values, we get
⇒
(c)
We know that,
Now,
⇒
By substituting the values, we get
⇒
45 is exactly half of 90
that means 45 is 50% of 90.
