The probability distribution below shows the likelihood that people were absent 0, 1, 2, 3, 4, or 5 days last month. the number of days absent probability 0 0.60 1 0.20 2 0.12 3 0.04 4 0.04 5 0.00
based on this information, what is the mean number of days absent?

the mean number of days absent is 0.72 days ( since 0.72 is not an integer, we can say that is the average number of days absent is close to 1 day)

Step-by-step explanation:

given a random variable X= number of days absent , the mean is calculated as:

mean = ∑ x * p(x)  , for all the x possible

where x = number of days absent and p(x) the probability of "x" number of days absent

therefore

mean = 0 * 0.60 + 1 * 0.20 + 2*0.12 + 3*0.04 + 4* 0.04 + 5* 0.00 = 0.72 days

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
