Answer:
After 23 years , the capital will get three times as big
Step-by-step explanation:
Firstly, let us write the compound interest formula
P = I( 1 + r)^n
Since we are considering a capital rise of 3 times
If I, the initial value is x, the P
value later will be 3x
Interest rate is 5/100 = 0.05
so we need the value of t
This will be;
3x = x(1 + 0.05)^t
3= 1.05^t
ln 3 = t ln 1.05
t = ln 3/ln 1.05
t = 23 years
200,000 is ten times 20,000

Answer with explanation:</h2>
Let 
be the population mean.
For the given claim , we have
Null hypothesis : 
Alternative hypothesis : 
Since alternative hypothesis is two-tailed , so the test is a two-tailed test.
Given : Sample size : n=220 ;
Sample mean: 
;
Standard deviation: 
Test statistic for population mean:
By using the standard normal distribution table of z , we have
P-value ( two tailed test ) : 
Since , the P-value is greater than the significance level of 
, it means we do not have sufficient evidence to reject the null hypothesis.
