Answer: There is sufficient evidence to reject the dealer's claim that the mean price is at least $20,500
Step-by-step explanation:
given that;
n = 14
mean Ж = 19,850
standard deviation S = 1,084
degree of freedom df = n - 1 = ( 14 -1 ) = 13
H₀ : ц ≥ 20,500
H₁ : ц < 20,500
Now the test statistics
t = (Ж - ц) / ( s/√n)
t = ( 19850 - 20500) / ( 1084/√14)
t = -2.244
we know that our degree of freedom df = 13
from the table, the area under the t-distribution of the left of (t=-2.244) and for (df=13) is 0.0215
so P = 0.0215
significance ∝ = 0.05
we can confidently say that since our p value is less than the significance level, we reject the null hypothesis ( H₀ : ц ≥ 20,500 )
There is sufficient evidence to reject the dealer's claim that the mean price is at least $20,500
36
Add all the sides up
15+15=30
3+3=6
30+6=36
Answer:
28BS
Step-by-step explanation:
Compré 30 libros a 40 bs cada uno;
Precio de costo = 30 × 40BS
= 1200 BS
Vendí unos pocos a 360 Bs, a 36 Bs cada uno.
Número de libros vendidos = 360 BS / 36 BS
= 10 libros
Número de libros restantes = 40 BS - 10 BS
= 30 BS
¿Cuánto debo vender cada uno de los libros restantes para no perder ni ganar nada?
Para no ganar ni perder nada, la cantidad total que queda para vender los libros =
1200BS - 360 BS = 840 BS
La cantidad para vender cada uno de los libros restantes sin ganar ni perder nada se calcula como:
840BS / Número de libros restantes
= 840BS / 30BS
= 28BS
