Probability is the link between Descriptive Statistics and Inferential Statistics. So get out your dice, coins, and cards. To get started, what is the probability of getting either a king or a red card if I pick a card at random from a standard deck of cards?

Also, let's say that a pro basketball player is a career 80% free throw shooter. Suppose the player attempts 4 free throws in a game. What is the probability that the player will make 2 of these 4 shots? As a first cut, do you think that the probability will be high or low?

Expert Solution

total number of cards in a deck=52

total numebr of king =4 and total red cards =26

as there are 2 card which are king as well red therefore number of cards which are king or red =4+26-2=28

hence probability of getting either a king or a red card =28/52=7/13

2) as expected number of success =np=4*0.8 =3.2 whcih is higher than 2 therefore probability of happenign that should be low.

probability that the player will make 2 of these 4 shots = =0.1536

Paired sample T test, Inferential statistics, descriptive statistics, Non-parametic inferential statistical procedures, Chi-square, Correlation, Independant-samples T test, Parametric inferential statistical procedures 1) This parametric statistical procedure is used when you have a dependent variable that is interval (1, 2, 3, 4, .....and so on), and an independent variable that is dichotomous (1=yes, 2=no for example). This tests compares the means (averages) of two samples and tells you if there are statistically significant differences between...

What is descriptive statistics? What is inferential statistics? Why do we care about the level of measurement of a variable? Why do we use n-1 rather than n in calculating sample variance? What are confounding variables, and what effect do they have on assessing cause-and-effect relationships? When would you prefer median to mean as a measure of central tendency? Why don’t we just sum the deviations from the mean to measure dispersion of a variable? When is it legitimate to...
