You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.16.

with h1 : p < 0.16 you obtain a test statistic of z=−2.683.

use a normal distribution calculator and the tet statistic to find the p-value accurate to 4 decimal places. it may be left-tailed, right-tailed, or 2-tailed.

p-value =

idk

Step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

definitely a. the others have almost all data points on one side of the line.
