In a random sample of 16 ATM transactions at a bank, the sample mean transaction time is 2 minutes with the sample standard deviation of 1.6 minutes. We can use this sample to construct a 95% confidence interval (in minutes) for the population mean transaction as, after applying the table below to get the Student’s t statistic. a. (1.1520, 2.8480)
b. (1.4652, 2.5348)
c. (1.2988, 2.7012)

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?
