In your problem:
p = 18.3% = 0.183
n = 130
The standard error can be calculated by the formula:
SE = √[p · (1 - p) / n]
= √[0.183 · (1 - 0.183) / 130]
= 0.0339
The standard error of the proportion is 0.034.
Answer:
B. 122, 257, 137
Step-by-step explanation:
The triangle inequality rule states that the sum of any two sides of a triangle must be greater than the third side. If A, B and C are sides of a triangle then A + B > C, A + C > B, B + C > A
Testing for the options:
1) 10, 20, 30
10 + 20 (= 30) is not greater than 30. It cannot form a triangle
2) 122, 257, 137
122 + 137 (259) is greater than 257. It can form a triangle
3) 8.6, 12.2, 2.7
8.6 + 2.7 (11.3) is not greater than 12.2. It cannot form a triangle
4) 1/2, 1/5, 1/6
1/5 + 1/6 (11//30) is not greater than 1/2. It cannot form a triangle
No more than in terms of math means less than or equal to.
P = 2l + 2w
{96 ≤ 2l + 2w
{L ≥ w - 4
Here we see a system of linear inequality in two variables.
You finish.
Answer:
A) Case A we dont rally have a nrmal distribution in case C
(See step by step explanation)
Step-by-step explanation:
Normal Distribution curve is a function of mean and standard deviation with these values we can plot the curve. The mean usually denoted by μ will show the most frecuent value of the population ( or sample ) and the standard deviation is a measure of the spread of the values around the mean. If we assume that for hitting the axis we should understand that the two given values are the end of the curve, then we can evaluate how spread is each of the curve then:
case A 115 - 75 = 40
case B 72 - 48 = 24
case C We do not touch x -axis in this case so curve is open we can find distribution values (theoretically) from -∞ to +∞ we dont really have a normal distribution in this case.
case D 38 - 28 = 10
Then if we dismiss case C the biggest standard deviation will be case A.
Note: we do not need to calculate standard deviation we just need to look how width it is
