Answer:
0.017559
Step-by-step explanation:
Data provided:
Probability of Households Having cable TV, p₀ = 76% = 0.76
Therefore,
The probability that the Households not having cable TV = 1 - 0.76 = 0.24
Sample size, n = 225 households
sample proportions is less than 82% i.e p = 0.82
Now,
The standard error, SE = ![\sqrt{\frac{p_0(1-p_0)}{n}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bp_0%281-p_0%29%7D%7Bn%7D%7D)
or
SE = ![\sqrt{\frac{0.76(1-0.76)}{225}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B0.76%281-0.76%29%7D%7B225%7D%7D)
or
SE = 0.02847
and,
![Z=\frac{p-p_0}{SE}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bp-p_0%7D%7BSE%7D)
or
![Z=\frac{0.82-0.76}{0.02847}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7B0.82-0.76%7D%7B0.02847%7D)
or
Z = 2.107
therefore,
P(sample porportions < 0.82) = P(Z < 2.107)
now from the p value from the Z table
we get
P(sample porportions < 0.82) = 0.017559

Answer:
x = -36
Step-by-step explanation:
5 +
= -1
= -1 - 5
= -6
x = -6 * 6
x = -36
Answer: 70-27x = 50-20x
Step-by-step explanation: First you do 7 x 10 which equals 70 then 7 x -3x equals -27x. Next you do 5 x 10 which is 50 next you do 5 x -4x equals -20x. So your answer is 70-27x = 50-20x
