An investment analyst wants to examine the relationship between a mutual fund's return, its turnover rate, and its expense ratio. She randomly selects 10 mutual funds and estimates: Return = ₀ + ₁Turnover + ₂Expense + , where Return is the average five-year return (in %), Turnover is the annual holdings turnover (in %), Expense is the annual expense ratio (in %), and is the random error component. A portion of the regression results is shown in the accompanying table.

	df	SS	MS	F
Regression	2	93.33	46.67	4.90
Residual	7	66.69	9.53
Total	9	160.02
	Coefficients	Standard Error	t-stat	p-value
Intercept	30.60	4.30	7.12	0.000
Turnover	0.13	0.06	2.23	0.061
Expense	0.90	4.08	0.22	0.831

a. Predict the return for a mutual fund that has an annual holdings turnover of 60% and an annual expense ratio of 1.5%.

b. Interpret the slope coefficient for the variable Expense.

c. Calculate the standard error of the estimate.

d. Calculate and interpret the coefficient of determination.
