Answer:
The claim on the M&M’s website is not true.
Step-by-step explanation:
A Chi-square test for goodness of fit will be used in this case.
The hypothesis can be defined as:
<em>H</em>₀: The observed frequencies are same as the expected frequencies.
<em>Hₐ</em>: The observed frequencies are not same as the expected frequencies.
The test statistic is given as follows:
Here,
= Observed frequencies
= Expected frequency.
The chi-square test statistic value is, 14.433.
The degrees of freedom is:
df = <em>k</em> - 1 = 6 - 1 = 5
Compute the <em>p</em>-value as follows:
*Use a Chi-square table.
The significance level is, <em>α</em> = 0.05.
p-value = 0.013 < <em>α</em> = 0.05.
So, the null hypothesis will be rejected at 5% significance level.
Thus, concluding that the claim on the M&M’s website is not true.
Answer:
El mayor lado del rectángulo es de 10 cm
Explicación paso a paso:
Perímetro de un rectángulo: es el doble de la suma de sus lados
P = 2 (a+b)
a: es el ancho del rectángulo
b: es el largo del rectángulo
Uno de los lados es 6cm mas que el otro lado
b= a + 6 cm
Sustituimos en la ecuación de perímetro:
28cm /2 = a+a+6cm
14cm = 2a +6 cm
14cm-6cm = 2a
a = 4 cm
b = 10cm
El mayor lado del rectángulo es de 10 cm
