Write only a number as your answer Question 3 (1.1 points) The federal government has enacted maximum alowable standards for air pollutants such as oaone. LetXbe thenumber of days per year that the level of air pollution exceeds the standard certain city. The probability distribution of Xis given Find the probabilty that the standard is exceeded on at least one day. write only a number as your answer, Round to two decimal places (for example 0.53), Do not write as a 0.67 Question 4 (1.1 points) Find the mean of the random variable with the following probability distribution write only a number as your answer Round to one decimal place (for example: 6.4) Question 5 (1.1 points) number of people were asked how many days they would wait to seek medical treatment if they were suffering pain that interfered with their ability to work. The results are presented in the following table. Consider this collection of people to be a population. Let Xbe the number of days for a person sampled at random from this person would wait more than 2 days. population. Find the probability that a write only a number as your answer Round to four decimal places (or example 0.5319). Do not write as a

Explanation / Answer

2) Since we know that the sum of all probabilities should come out as 1.

So 0.31+0.41+0.06+x=1

x + 0.78 = 1

x = 0.22

3) P(atleast 1) = 1-P(less than 1)

= 1-0.33

= 0.67
