Answer:
The correct option is F
Since the test statistics<u> is outside </u>the rejection region , <u>we fail to reject </u>the null hypothesis ,There<u> is no</u> statistically significant evidence to reject the claim
Step-by-step explanation:
From the question we are told that
The claim is 
Hence
The null hypothesis is 
The alternative is 
Generally the test statistics is mathematically represented as
=> 
=>
Generally the degree of freedom is mathematically represented as
From the student t-distribution table the critical value of 
at a degree of freedom of 8 is
Since the 
is outside the rejection region , we fail to reject the null hypothesis ,There is no sufficient evidence to reject the claim

Answer:
Explanation:
Hola. Puesto que tu pregunta está en español, te responderé en el mismo lenguage.
Estas son las posibilidades dadas por la combinación moneda/dado
Número de combinaciones
Moneda: prenda
Cara: vestido 1 de 2: 1/2
Sello: falda 1 de 2: 1/2
Dado: color
Par: negro 3 de 6: 3/6
Impar: café 3 de 6: 3/6
En total son 2 × 6 resultados: 12 (incluye resultados repetidos, no son todos diferentes entre sí)
¿Cuántas combinaciones tienen vestido y color negro?
Es decir: moneda = cara y dado = par
Por tanto, la probabilidad de vestido negro es:
- 3 de 12 = 3/12 = 1/4 ← respuesta
Hay otras formas de resolverlo. Por ejemplo;
Como los resultados de lanzar la moneda y el dado son independientes:
- P(Vestido∩negro) = P(Vestido) × P(Negro)
- P(Vestido) = 1/2
- P(Negro) = 3/6 = 1/2
- P(Vestido) × P(Negro) = 1/2 × 1/2 = 1/4 ← mismo resultado
