Answer:
(a) 
(b) 
Step-by-step explanation:
Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).
So
Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.
(a)
Therefore, to answer question (a) we use the following equation presented in the attached image:
Where:
Then:
(b)
For part (b) we have:
Answer:
$5107.20
Step-by-step explanation:
His pay after he was caught once
133x 8=1064
1064x 20% = 212.8
1064-212.8=851.2
1064x 4= 4256
4256+ 851.2=5107.2

Answer:
Step-by-step explanation:
∠Q = 180-∠T = 89°
∠S = 360-∠T-∠Q-∠R = 360-91-89-27 = 153°
The confidence interval in the form p+E is p ± E = 0.7725 ±0.435
<h3>How to rewrite the
confidence interval?</h3>
The confidence interval is given as:
0.555< p < 0.99
To rewrite the above expression in the form p+E, we use the following equations
p = (0.99 + 0.555)/2 = 0.7725
E = (0.99 - 0.555) = 0.435
So, we have:
p ± E = 0.7725 ±0.435
Hence, the confidence interval in the form p+E is p ± E = 0.7725 ±0.435
