Answer:
0.05
Step-by-step explanation:
P value that is less than 0.05, that is P < 0.05 means that the null hypothesis is false and should be rejected. If the P value is greater than 0.05, that is P > 0.05, it means the null hypothesis is true. The P value is also called the calculated probability value. P value subtracted from 1 is the probability that the alternative hypothesis is true.
The number of handshakes that will occur in a group of eighteen people if each person shakes hands once with each other person in the group is 153 handshakes
In order to determine the number of handshakes that will occur among 18 people, that is, the number of ways we can choose 2 persons from 18 people.
∴ The number of handshakes = 






∴ The number of handshakes = 153 handshakes
Hence. 153 handshakes will occur in a group of eighteen people if each person shakes hands once with each other person in the group.
