If the confidence level is increased from 90% to 99% for an srs of size n , the width of the confidence interval for the mean μ will:

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will increase.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

If the confidence level is increased from 90% to 99% for an SRS of size n , the width of the confidence interval for the mean μ will:

We know that when confidence level decreases from a value to a lower value, then the confidence interval for the mean decreases.

When confidence level increases from a value to a higher value, then the confidence interval for the mean increases.

When we will increase the confidence level from 90% to 99%, the width of the confidence interval for the mean will also increase, so it will become wider.

Therefore, the correct word for our given statement is increase.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
