Respuesta, explicación paso a paso:

A. Con el ejercicio anterior podemos deducir que se trata de un número de ventas en una tienda de comestibles, la frecuencia relativa para la cantidad de unidades vendidas se muestra a continuación:

unidades vendidas. frecuencia relativa. frecuencia acumulada. intervalo de números aleatorios

30. 0.16. 0.16. 0.00 <0.16

40. 0.24. 0.4. 0.16 <0.4

50. 0.3. 0.7. 0.4 <0.7

60. 0.2. 0.9. 0.7<0.9

70. 0.1. 1. 0.9<1

B. Para el siguiente punto, nos dan algunos números aleatorios y se comparan con la simulación de 10 días de ventas:

unidades aleatorias

número vendido

0.12. 30

0.96. 70

0.53. 50

0.80. 60

0.95. 70

0.10. 30

0.40. 50

= 0.1165 Step-by-step explanation: In statistics, the binomial distribution involves two possible outcomes. With ''n'' representing the number of trials in an experiment, these tables can be utilized to find the probability of achieving a specific number of successes within the experiment. P=14% = 0.14, n=30. Here, binomial distribution cumulative tables are applied. Thus, P(More than 7) = P(x > 7) = 1 - P(x < 7) = 1 - P(x ≤ 6) = 1 - 0.8835 = 0.1165.

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zina [12379]

P(S) = Probability of Smash = 0.05 (5%)
P(M) = Probability of Modest = 0.5 (50%)
P(F) = Probability of Flop = 0.45 (45%)
Based on this, we utilize the model for discrete random variables, leading to:
E(X) = (0.05 * 5.2) + (0.5 * 0.9) + (0.45 * 0)
= 0.26 + 0.45 + 0
= 0.71 Mill'
