Answer: 384 or 528 depending if you have to add the interest he already earned
Step-by-step explanation:
1st integer: x
2nd integer: x+1
Add them up: 2x+1= 145145
2x= 145146
x=72,573
Answer;
1st integer: 72573
2nd integer; 72,574

Answer:
b. There is sufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
Step-by-step explanation:
Not significant,accept null hypothesis that population proportion = 0.65
When we accept the null hypothesis that P= 0.65
Then only option b is correct which states that there is sufficient evidence to support that population proportion is exactly 0.65 .
1) We obtain a P - value of 0.0522 which is greater than 0.5 indicating that the null hypothesis is not rejected.
The rejection region for this right-tailed test is z > 1.64
2) Test Statistics
z= p`-p0/ sqrt(p0(1-p0)/n)
The z-statistic is computed as follows:
z= 0.75-0.65/ √(0.65*0.35)60
z= 1.624
3) Decision about the null hypothesis
Since it is observed that z = 1.624 is less than z ∝=1.64, it is then the null hypothesis is not rejected.
5400*0.04(rate)=216
Because it's simple interest for 7 years, 216*7 should be the answer
So $1512
