Answer:
POOOOOOOOOOOOOOOOOOG
Step-by-step explanation:
Using the normal distribution, there is a 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation
.
For this problem, the parameters are given as follows:

The probability is the <u>p-value of Z when X = 16 subtracted by the p-value of Z when X = 15</u>, hence:
X = 16:

By the Central Limit Theorem


Z = 2.11
Z = 2.11 has a p-value of 0.9826.
X = 15:


Z = 0
Z = 0 has a p-value of 0.5.
0.9826 - 0.5 = 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.

Answer:
77 goles
Step-by-step explanation:
Un futbolista ha marcado 2/9 del número de goles marcados por su equipo.
Otro anotó una cuarta parte del resto.
El resto = 1 - 2/9
= 7/9
De ahí que otro futbolista anotó
= 1/4 de 7/9
= 7/36
Si los otros jugadores han marcado 45 goles
Tenemos que averiguar la fracción de goles que marcó el otro jugador
Deje que el número total de goles marcados por el equipo durante la temporada = 1
Por lo tanto:
1 - (2/9 + 7/36)
1 - (8 + 7/36)
1 - 15/36
1 - 5/12
= 7/12
¿Cuántos goles marcó el equipo a lo largo de la temporada?
El número total de goles que marcó ese equipo se calcula como:
7/12 × x = 45
Donde x = número total de goles
7x / 12 = 45
Cruz multiplicar
7x = 45 × 12
x = 45 × 12/7
x = 77,142857143
Aproximadamente = 77 goles
