Answer:
The estimate of a population proportion is approximately 541.
Step-by-step explanation:
We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula
n = pq ((Z/2) / E)^2
As, p is not defined so we use the standard p and q which is 0.5 and 0.5.
The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.
Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula
n = (0.5)×(0.5) × (2.326/0.05)^2
n = 541.027
n ≅ 541.
<h3><u>68 inches</u></h3>
Because we know how large each hand is, we can multiply the number of hands by the amount of inches each one represents to find the total number of inches.
17 * 4 = 68
Answer:
= 8p
Step-by-step explanation:
Steps
2p · 4
Remove parentheses: (a) = a
= 2p · 4
Multiply the numbers: 2 · 4 = 8
= 8p
