1 answer:

6 0

OptionAStep-by-step explanation:95% confidence interval is obtained using the following formulaCOnfidence interval lower bound = mean - critical value * sigma/sq rt nand upper bound = mean + critical value*sigma/sq rt nThus margin of error = critical value*sigma/rt nvaries indirectly as n provided others are remaining the same.Hence lower sample indicates higher margin of errorOut of 4 options given we find that 1 option has maximum margin of error as 21%Hence option. A is most likely coming from a small sample.

Josephine earned a 15% return on her investments last year. If the inflation rate that year was 4%, what is her real rate of ret

MaRussiya [10]

Answer:

B. 11%

Step-by-step explanation:

Using the formula

Real rate of return = nominal rate - inflation rate

Note that the nominal rate of a business is the return on investment in a particular year.

Therefore if Josephine earned a 15% return on her investments last year, her nominal rate is also 15%

Since the inflation rate is 4%

Rate of return = 15%-4%

Rate of return = 11%
