Question 30 An investor would like to know if their stock portfolio average CAGR (compound annual growth rate) is different from 10%. From a sample of 30 periods, the average CAGR was 12.2% with standard deviation of s-996. Calculate the 95% confidence interval. Perform the appropriate one-sample test with results ? Based on the one-sample t test, conclude that the average CAGR is significantly different from 10%. Based on the one-sample Z test, conclude that the average CAGR is NOT significantly different from 10%. Based on the one-sample Z test, conclude that the average CAGR is significantly different from 10%. Based on the one-sample t test, conclude that the average CAGR is NOT significantly different from 10%.

Explanation / Answer

Question 30

Solution:

Test Hypothesis:

H0 : ? = 10

HA : ? ? 10

Mean Sample Mean Std. Err. DF T-Stat P-value

? 12.2 1.6431677 29 1.3388774 0.191

Since p - value is greater than 0.05, we do not reject Ho.

Hence,

Option d) Based on the one-sample t test, conclude that the average CARG is NOT significantly different from 10%.
