Following are the data on percentage of investments in energy
Following are the data on percentage of investments in energy securities and tax efficiency from Exercise 14.16.
At the 2.5% significance level, do the data provide sufficient evidence to conclude that percentage of investments in energy securities and tax efficiency are negatively linearly correlated for mutual fund portfolios?
Presuming that the assumptions for regression inferences are met, perform the required correlation t-tests, using either the critical-value approach or the P-value approach.
