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.
The amount he needs to pay is $ 28753.61.
Step-by-step explanation:
Given,
Principal (P) = $ 8000
Time (T) = 10 years
Rate of interest (R) = 13%
The payment will be quarterly so, n = 4
To find the amount of compound interest.
Formula
Amount =
Now,
Putting the values of P, T, n and R we get,
Amount = 8000(
= 28753.61 (approx)
