Answer:

difference in the proportion = 0.0452

Step-by-step explanation:

x1 = 27, n1 = 193,

p1 = 27/193

p1 = 0.1399

x2 = 16, n2 = 169,

p2 = 16/169

p2 = 0.0947

a) The best estimate for the difference in the proportion of smokers, using male proportion minus female proportion is 0.0452. Male smokes more than females in given sample.

p1 - p2 = 0.1399 - 0.0947

p1 - p2 = 0.0452

Anon25 [30]

Answer and Step-by-step explanation:

Theoretical probability is expected probability of an occurrence hence the name theoretical. It is theoretical and not practical as it has not been experimented or actually become practical. Experimental probability on the other hand is probability that has been experimented- it is the result of test of probability on the actual population.

In the case above, the theoretical which is the expected probability that has not been experimented is 1/2 of getting Red cards. This probability is theoretical and therefore may change when tested. Hence the different result of 7 Red and 13 blacks with 20 cards picked when experimented
