true or falseSuppose a 95% confidence interval for the population proportion of students at your school who reg-ularly drink alc

ohol is (0.61,0.67). The inference is that you can be 95% confident that the sampleproportion falls between 0.61 and 0.67.

Answer:

The provided statement is False.

Step-by-step explanation:

A (1 - <em>α</em>)% confidence interval for population proportion is given by:

CI=\hat p\pm z_{\alpha/2}\times \sqrt{\frac{\hat p(1-\hat p)}{n}

The 95% confidence interval for the population proportion of students at your school who regularly drink alcohol is,

<em>CI</em> = (0.61, 0.67)

A (1 - <em>α</em>)% confidence interval for a population parameter implies that there is (1 - <em>α</em>) probability that the true parameter value is contained in the interval.

Or, there is (1 - <em>α</em>)% confidence that the confidence interval consists of the true population parameter value.

The 95% confidence interval for the population proportion of students who  who regularly drink alcohol indicates that there is 0.95 probability that the true proportion values is included in the interval (0.61, 0.67).

Or, we are 95% confident that the 95% confidence interval, i.e. (0.61, 0.67) includes the true proportion of students who  who regularly drink alcohol.

Thus, the provided statement is False.

Can you put these number from least to greatest?
Eva8 [605]

The correct order would be:

5/64 x 3, 1/16 x 3, 3/32 x 4, 11/64 x 4, 7/16 x 3, 3/4 x 2, 3/8 x 4, 1 7/8 x 4, 2.25 x 2, 1.5 x 4, 3 3/8 x 3, 3.75 x 3

First we have to take all of the numbers and do the multiplication. It's often easiest to turn them in to decimals so that you have a common form.

3/32 x 4 = 3/8 = .375

3/4 x 2 = 3/2 = 1.5

1 7/8 x 4 = 15/4 = 3.75

2.25 x 2 = 4.5

1.5 x 4 = 6

3/8 x 4 = 3/2 = 1.5

5/64 x 3 = 5/32 = .156

3.75 x 3 = 11.25

1/16 x 3 = 3/16 = .1875

7/16 x 3 = 21/16 = 1.31

3 3/8 x 3 = 81/8 = 10.125

11/64 x 4 = 11/16 = .687

Now we can use those to put in order.

5/64 x 3 = 5/32 = .156

1/16 x 3 = 3/16 = .1875

3/32 x 4 = 3/8 = .375

11/64 x 4 = 11/16 = .687

7/16 x 3 = 21/16 = 1.31

3/4 x 2 = 3/2 = 1.5

3/8 x 4 = 3/2 = 1.5

1 7/8 x 4 = 15/4 = 3.75

2.25 x 2 = 4.5

1.5 x 4 = 6

3 3/8 x 3 = 81/8 = 10.125

3.75 x 3 = 11.25

Which if you are looking for without the extra terms, you can check the answer at the top.

Constructing a brick staircase: A brick staircase has a total of 30 steps. The bottom step requires 100 bricks. Each successive
galben [10]
A) The first step needs 100 bricks, the second needs 98, the third needs 96, and so on. Therefore the number of bricks for the nth step is: a_n = a_1 + d(n-1), where a_1 = 100 (the first term), d = -2 (difference).
a_n = 100 - 2(n-1) = 102 - 2n, and for the 30th step, a_30 = 102 - 2*30 = 42. So the top step will need 42 bricks.

b) The total staircase will need: 100 + 98 + 96 + ... +  44 + 42, and there are n = 30 terms. Using the formula for the sum of an arithmetic sequence:
S = (a_1 + a_n)*n/2 = (100 + 42)*30/2 = 2130
Therefore, 2130 bricks are required to build the entire staircase.
