Assume we need to estimate the mean of a normally-distributed population with great accuracy. Specifically, for significance lev

bulgar [2K]

Answer:

$n = 2662.56\sigma^2$

Step-by-step explanation:

We are given the following in the question:

Significance level = 0.01

Width of interval = 0.1

Population variance = $\sigma^2$

We have to find the sample size so that the width of the confidence interval is no larger than 0.1

$z_{critical}\text{ at}~\alpha_{0.01} = \pm 2.58$

Formula for sample size:

$n = \displaystyle\frac{z^2\sigma^2}{E^2}$

where E is the margin of error. Since the confidence interval width is 0.1,

$E = 0.05$

Putting these values in the equation:

$n = \displaystyle\frac{(2.58)^2\sigma^2}{(0.05)^2} = 2662.56\sigma^2$

So, the above expression helps us to calculate the sample size so that the width of the confidence interval is no larger than 0.1 for different sample variances.

(50 points!) Whats 7x + 5z(x-z) ÷ 9y, when x = 5, z = 8, and y = 23. Whoever Gives me an answer AND REALLY GOOD EXPLANATION FIRS

Oliga [24]

Answer: First we will substitute the numbers given for the variables.

Then we will use order of operations to simplify.

7x + 5z(x - z) ÷ 9y would be equal to

7(5) + 5(8) * (5 - 8) ÷ 9(23)

Simplify:

35 + 40(-3) ÷ 207

Use order of operations to multiply 40 and -3; the equation now looks like:

35 + (-120) ÷ 207

Use order of operations to divide -120 and 207; the equation now looks like:

35 + (-0.6)

Add 35 and -0.6:

34.4

The solution to this equation is 34.4.
