A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.

Answer:
Entonces Patricia necesitara 4 estampas de $3 dolares y 6 estampas de $1 dolar
Step-by-step explanation:
Cuatro estampas de tres dolares cada una es:
3 × 4 = 12
Ahora necesitamos encontrar cuantas estampas mas Patricia puede comprar. Podemos hacer esto restando 12 a 18, que es el costo total de las estampas menos del valor encontrado
18 - 12 = 6
Ahora sabemos que Patricia necesita 6 dolares de estampas ($1 estampas) para acompletar las 10 estampas dando un total de $18 dolares.
6 × 1 = 6 < sumar 6 de 12
12 + 6 = 18
Entonces Patricia necesitara 4 estampas de $3 dolares y 6 estampas de $1 dolar
