Answer:

$f(x+ h) = 6x + 6h -3$

$f(x+ h) - f(x) = 6h$

$\frac{f(x + h) - f(x)}{h} = 6$

Step-by-step explanation:

From the question the given equation is

$f(x) = 6x -3$

Considering A

$f(x+ h) = 6(x + h) -3$

=> $f(x+ h) = 6x + 6h -3$

Considering B

$f(x+ h) - f(x) = 6x +6h -3 - (6x-3)$

$f(x+ h) - f(x) = 6h$

Considering C

$\frac{f(x + h) - f(x)}{h} = \frac{6h}{h}$

$\frac{f(x + h) - f(x)}{h} = 6$

In a randomly selected sample of 100 students at a University, 81 of them had access to a computer at home. Give the value of th

astra-53 [7]

Answer:

The value of the standard error for the point estimate is of 0.0392.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$
