Hello here is the missing data to your question
x P(x)
0 0.167
1 0.3289
2 0.2801
3 0.149
4 0.0382
5 0.0368
The theoretical values are lower than the approximate values and the property illustrated is the mean and standard deviation
A) 1.6729
B) 1.234061
C) 1.84
D) 1.462874
Step-by-step explanation:
A) calculate the theoretical mean
theoretical mean (u) = summation of ;
= 0(0.167)+1(0.3289)+2(0.2801)+3(0.149)+4(0.0382)+5(0.0369)
= 1.6729
B) calculate the theoretical standard deviation
theoretical standard deviation = =
=
= 1.234061
C) calculate the approximate mean
the generated data used for calculation is added below
mean (x) = =
= 46/25 = 1.84
D) calculate the approximate standard deviation
std =
=
= = 1.462874
