Answer:
C.
Step-by-step explanation:
Hypothesis testing procedure:
Hypothesis:
The null hypothesis will be the variances of sales of two musical stores are equal and the alternative hypothesis will be the variances of sales of two musical stores are not equal
Level of significance: alpha=0.05
Test statistic: F=variance A/variance B=(30)^2/(20)^2=900/400=2.25
P-value: p=0.107
As the alternative hypothesis mentioned that the variances are not equal this leads to two tailed test. so the p-value is calculated using excel function 2*F.DIST.RT(2.25,24,15).
Conclusion:
The p-value seems to exceed the alpha=0.05 and this depicts that the null hypothesis should not be rejected.
The dollar amount of the discount is 440 - 154 = $286.
Therefore the percentage discount for the sale is given by:
fraction form: 8/3 * 5/7 = 1 19/21
