Is it correct to say that the probability that μ is in the specified interval is 99%? explain?

1 answer:

7 0

For a 99% confidence interval for μ based on a simple random sample.

Part (a):

Is it correct to say that the probability that μ is in the specified interval is 99%? Explain.

No. The probability that μ falls inside the interval is 0 or 1.

Rather we say that we are 99% confident that μ will fall inside the interval.

Part B:

Is it correct to say that in the long run, if you computed many, many confidence intervals using the prescribed method, about 99% of such intervals would contain μ?

Yes. 99% of intervals constructed using this method will capture the population mean μ.

Make a the subject of the formula:p=2a-3

IceJOKER [234]

To make a the subject we proceed as follows:
p=2a-3
add 3 on both sides
3+p=2a-3+3
simplifying the above gives us:
3+p=2a
divide both through by 2
3/2+p/2=(2a)/2
thus
a=3/2+p/2

Answer:

${5}^{8} {x}^{6}$

Step-by-step explanation:

$\bigg( \frac{125 {x}^{ - 3} }{ {5}^{ - 3} \times 25 \times {x}^{ - 6} } \bigg)^{2} \\ \\ = \bigg( \frac{ {5}^{3} {x}^{ - 3} }{ {5}^{ - 3} \times {5}^{2} \times {x}^{ - 6} } \bigg)^{2} \\ \\ = {( {5}^{3 + 3 - 2} {x}^{ - 3 + 6} })^{2} \\ = {( {5}^{6 - 2} {x}^{3} )}^{2} \\ = {( {5}^{4} {x}^{3}) }^{2} \\ = {5}^{4 \times 2} {x}^{3 \times 2} \\ = {5}^{8} {x}^{6} \\$

What inequality represents the sentence below? The product of a number and 5 is no more than 8.

Elanso [62]

5x<=8

5x is the product of an unknown number and 5 and that could be less than or equal to 8. It should be the symbol that is on top of each other but I can't type that here.

Hope that helps.
