Answer: Choice B) experimental probability is larger
-----------------------------------------------------------------
There are 3 odd numbers (1,3,5) out of 6 total (1,2,3,4,5,6) on the number cube. So theoretically, the chances of rolling an odd number are 3/6 = 1/2 = 0.5
When we do the experiment, we roll an odd number 325 times out of 500 trials total. So the experimental probability is 325/500 = 0.65
Comparing the results of 0.5 and 0.65, we see that 0.65 is larger. So the experimental probability is larger.
Note: with a large number of trials, the experimental probability should get closer and closer to the theoretical probability. This is assuming that all trials are independent of one another and the number cube is properly weighted.
Responder:
Los 48.1875m
Explicación paso a paso:
Si se colocaron 16 postes para soportar 385,5 m de cable telefónico, esto significa que la distancia entre los 16 postes es de 385,5 m.
Debemos encontrar la distancia entre 2 postes;
16 puestos = 385,5 m
2 puestos = x
Cruz multiplicar
16 veces = 2 * 385,5
16x = 771
x = 771/16
x = 48,1875 m
Por lo tanto, la distancia entre 2 postes es de 48,1875 m.
Answer:
(0.2744; 0.3206)
Step-by-step explanation:
The z-score for a 95% confidence interval is Z = 1.960.
The proportion of Americans in the sample who believe that they have an active imagination is given by the number of people who answered that "they definitely did", divided by the total sample of n =1506.
The confidence interval for a proportion 'p' is:
The 95% confidence interval is: I = (0.2744; 0.3206)
