Answer:
The answer is 12 (so the letter B)
Step-by-step explanation:
9+15+17+18+6+20+8+5+18+18+10+5+ 14+12+10+7=192
Then if you count the amount of numbers you find that there is 16 numbers.
You then do 192 ÷16 which gives you 12
Answer:
a) The cumulative distribution function would be given by:
x 0 1 2 3 4 5
F(X) 0.05 0.15 0.30 0.55 0.9 1
b)
And replacing we got:
Step-by-step explanation:
For this case we have the following probability distribution function given:
x 0 1 2 3 4 5
P(X) 0.05 0.1 0.15 0.25 0.35 0.1
We satisfy the conditions in order to have a probability distribution:
1)
2)
Part a
The cumulative distribution function would be given by:
x 0 1 2 3 4 5
F(X) 0.05 0.15 0.30 0.55 0.9 1
Part b
For this case we want to find this probability:
And replacing we got:
