Step-by-step explanation:
The simple interest on the balance of $3,500 is 8.88%
The simple interest on the balance of $7,500 is 7.48%
What is simple interest?
The simple interest on a credit card is the annual interest multiplied by the credit card balance, in other words, the total interest paid on both credit cards in the year under review summed up to $797.
Let us assume that simple interest on the credit card with a balance of $7500 is X
interest=$7500*X
The interest on the other credit card would be X+1.4%
interest in dollars=$3500*(X+1.4%)
total interest cost in dollars on both cards can be determined as the sum of the interest costs
total interest=$7500*X+$3500*(X+1.4%)
total interest=7500X+3500X+49
total interest=797
797=7500X+3500X+49
797=10000X+49
797-49=10000X
748=10000X
X=748/10000
X=7.48%
The simple interest on the credit balance of $7500 is 7.48%
The simple interest on the credit balance of $3,500=7.48%+1.4%
The simple interest on the credit balance of $3,500=8.88%

Answer:
Option a) Compare the level of significance to the confidence coefficient.
Step-by-step explanation:
We are given the following information in the question:
We are performing a two-tailed test hypothesis. We can follow the following approaches:
Option a) Compare the level of significance to the confidence coefficient.
This cannot be used to perform hypothesis.
Option b) Compare the value of the test statistic to the critical value.
If the test statistic lies in the acceptance region evaluated by the critical value, we accept the null hypothesis. If not, we reject the null hypothesis.
Option c) Compare the confidence interval estimate of μ to the hypothesized value of μ.
If the estimated population lies in the calculated confidence interval, we accept the null hypothesis otherwise, we reject the null hypothesis.
Option d) Compare the p-value to the value of α.
If the p-value is greater than the significance level, we accept the null hypothesis. If it is lower than the significance level, we reject the null hypothesis.
