Probability and Statistics

It is a numerical quantity that is assigned to the outcome of an experiment.

Two coins are tossed in an experiment. Which of the following list is the sample space?

• S= {HH, HT, TH, TT}

• S= {HH, TT}

• S= { HT, TH, TT}

• S= {HH, HT, TT}

Supposed two coins are tossed consecutively and we are interested in the number of heads that will come out. Determine the values of the random variable H (number of heads).

• 0,2,3,4

• 0,1,2,3

• 0,1,2

• 0,1,2,3,4

Nico label an x- axis with points earned and the corresponding y - axis with the number of players. He plot one against the other and he obtain a bar graph called a what?

If you had no idea what the answer to this four option multiple choice was and took a wild guess, what is the probability that you are correct?

Which of the following are the properties of a Normal Probability Distribution.

• The distribution curve is bell - shaped.

• The curve is symmetric about its center, the mean.

• The mean, the median, and the mode coincide at the center.

• The area under the curve is 1 or 100%

• The tails of the curve is asymptotic to the base line.

TRUE or FALSE: The standard normal distribution of a random variable is a normal distribution with mean =0 and standard deviation =1.

• TRUE

• FALSE

TRUE or FALSE: The area between 0 and a positive value z is the same as the area between 0 and -z.

• TRUE

• FALSE

TRUE or FALSE: The area that corresponds to z = 2.58 is the same as the area that corresponds to z = -2.58, which is A = 0.4951

• TRUE

• FALSE
