PLEASE HELP AND FAST PLEASE 2. To help evaluate the original report, draw a normal curve for the data Marjin-O'Heara
collected. Include the values of the mean and the first three standard deviations in your
sketch. (4 points: 1 point for the curve, 3 points for correct critical values)

3. The client was hoping for a likability score of at least 5.2. Use your sample mean and
standard deviation identified in the answer to question 1 to complete the following table for the
margins of error and confidence intervals at different confidence levels. Note: No further
calculations are needed for the sample mean. (6 points: 2 points for each completed row)

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

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?

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
