What is the appropriate z critical value for each of the following confidence levels? a. 95% d. 80% b. 90% e. 85%

95% confidence level

80% confidence level

90% confidence level

85% confidence level

Step-by-step explanation:

For a confidence level of x, the critical value of z is the value of z with a pvalue of p given by the following formula:

Then we look at the z-table to find Z with a pvalue of p.

a. 95%

Z with a pvalue of

So

d. 80%

Z with a pvalue of

So

b. 90%

Z with a pvalue of

So

e. 85%

Z with a pvalue of

So

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

cool stunts are flippin i think

sitting on a chair

and using stick feet
