The confidence interval for the difference p1 - p2 of the population proportion is (0.063, 0.329)
<h3>How to determine the confidence interval?</h3>
The given parameters are:
n₁ = 93; n₂ = 80
p₁ = 0.814; p₂ = 0.618
The critical value at 95% confidence interval is
z = ±1.96
So, we have:
Substitute known values in the above equation
Evaluate
This gives
CI = 0.196 ± 0.133
Expand
CI = (0.196 - 0.133, 0.196 + 0.133)
Evaluate
CI = (0.063, 0.329)
Hence, the confidence interval is (0.063, 0.329)

Step-by-step explanation:
Figure RSTU and Figure XWZY are the same meaning it has the same side lengths and angles. Also, if you reflect the shape the angle will be on the same side. The side lengths are not shown on Figure XWZY but they are the same.
Using probabilities, it is found that the expected profit of one round of this game is of $0.
A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- One of the two sides of the coin are heads.
- 2 of the 6 sides of the dice are 3 or 6.
Hence, since the coin and the dice are independent, the <em>probability </em>of winning is:
The expected value is the <u>sum of each outcome multiplied by its respective probability</u>.
In this problem:
probability of earning $30.
probability of losing $6.
Then:
The expected profit of one round of this game is of $0.

Perimeter:24 units
Horizontal side is 7 units and vertical side is 5 units. You first multiply 7 by 2 and 5 by 2. You will get 14 and 10. Then, you add 14+10. The answer would be 24.
