You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly more than 0.21. With H1 : p
>
>
0.21 you obtain a test statistic of
z
=
2.831
z
=
2.831
.
Use a normal distribution calculator and the test statistic to find the P-value accurate to 4 decimal places. It may be left-tailed, right-tailed, or 2-tailed.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
