Question

tnis p your answer sheets 1. A single card is drawn from 52-card deck (10) Let A denotes the event that the card is red and B denotes the e is spade. Are the events being? a) Mutually exclusive? b) Dependent? What is your conclusion and B? Any exception? 2. Two team (A and B) play a series of baseball games. The team who v five-game-series wins the series. Consider A has home-field advantag probability of winning 0.7 if it plays in its field) and opponent-field di means A has probability of winning 0.2 if it plays in opponents field) on A team's field and played alternately between A and B team's fie probability that series will be won by B in four games . Wild boar population weight has standard deviation of 50 lb a) Find the probability of existence of a random sample (size 10 b) For the same sample size, find the probability of the mean w c) Interpret a) and b) in terms of sampling error and explain wh t 5 lb: of population mean weight. population mean weight. for a person without knowledge of statistics. A random sample of size 64 generated a sample mean of 80. Th deviation is 16. a) Calculate the confidence interval (CI) for 95% confidence lev population mean.

Answer 1

1)

a)  
spade and red = 0 cards  
since there is no common elements between two events, so these are muually exclusive events  
  
b)  
P(A)=26/52  
P(B) = 13/52  
P(A n B) =0  
since, P(A)*P(B)╪P(A n C)  
so, events are dependent
