Complete the statement by filling in the blanks: When constructing a confidence interval, if the level of confidence increases,

Yuki888 [10]

Answer:

$\hat p \pm z_{\alpha/2} SE_{\hat p}$

And for this case the margin of error would be:

$ME= z_{\alpha/2} SE_{\hat p}$

If the level of confidence increase we can conclude that the value of $z_{\alpha/2}$ would increase and the the confidence interval would be wider, since the margin of error increase.

c. Increase; wider

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Solution to the problem

Let's assume that we have a parameter of interest $p$ and we want to estimate the value of p with $\hat p$ and in general the confidence interval if the distribution of p is normal is given by:

$\hat p \pm z_{\alpha/2} SE_{\hat p}$

And for this case the margin of error would be:

$ME= z_{\alpha/2} SE_{\hat p}$

If the level of confidence increase we can conclude that the value of $z_{\alpha/2}$ would increase and the the confidence interval would be wider, since the margin of error increase.

c. Increase; wider

Find g(f(x)) if<br> f(x) = x + 1<br> g(x) = x3

andreyandreev [35.5K]

Answer:

g(f(x)= x^3+3x^2+3x+1

Step-by-step explanation:

the statement tell us:

f(x) = x + 1

g(x) = x^3

so we have:

g(f(x)=(x + 1)^3

g(f(x)= x^3+3x^2+3x+1

Jerry left a $ 5.22 5.22 tip on a meal that cost $ 29 29. What percent of the meal's cost was the tip? What was the total co

Lubov Fominskaja [6]

I'm assuming that each price copied twice, since 5.225.22 isn't a number.

To find the percent, divide the tip by the meal cost:

5.22 ÷ 29 = 0.18 = 18%

Jerry left an 18% tip.

To find the total cost of the meal, add the tip and the meal cost:

5.22 + 29.00 = 34.22

The total cost if the meal, including tip, was $34.22.
