At a specific service station, 35% of the clients utilize normal gas, 35% use in addition to

gas, and 30% utilize premium. Of those clients utilizing ordinary gas, just 30%

fill their tanks. Of those clients utilizing also, 40% fill their tanks, though of

those utilizing top notch, 35% fill their tanks.

a. What is the likelihood that the following client will demand in addition to gas and not

fill the tank?

b. What is the likelihood that the following client fills the tank?

c. In the event that the following client doesn't fill the tank, what is the likelihood that ordinary

gas is mentioned? In addition? Premium?

Elite sprinters complete a long distance race in a normal of 145 minutes with a standard deviation of 14 minutes.

An example of 49 a-list long distance runner is taken.

What is the likelihood that the example mean (normal) is between 142 minutes and 146 minutes?

c. Discover P(12

Consider the following conditional density function extracted from a joint bivariate normal density function. A student thinks that there is a mistake, that the two variables were uncorrelated. It the student is correct, and everything else is correct, what are the correct Hyla-3.5 and f(y | x) ~ NUbe an = 25+0.42 TE (3.5 - 3) = 2.60, Jax an = (1 -0.4')0.4" = 0.36660) Select one: A bivariate normal density with variance 0.4 and mean Q b.
