Consider three stock funds, which we will call Stock Funds 1, 2, and 3. Suppose that Stock Fund 1 has a mean yearly return of 15.50 percent with a standard deviation of 19.00 percent; Stock Fund 2 has a mean yearly return of 9.70 percent with a standard deviation of 15.10 percent, and Stock Fund 3 has a mean yearly return of 10.80 percent with a standard deviation of 15.90 percent. (a) For each fund, find an interval in which you would expect 95.44 percent of all yearly returns to fall. Assume returns are normally distributed. Note: Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.

a Consider the curve \( y=x^{2}+a x+b \quad \) where \( a \) and \( b \) are constants. The tangent to this curve at the point where \( x=1 \) is \( 2 x+y=6 \). Find the values of \( a \) and \( b \). b Consider the curve \( y=a \sqrt{x}+\frac{b}{\sqrt{x}} \quad \) where \( a \) and \( b \) are constants. The normal to this curve at the point where \( x=4 \) is \( 4 x+y=22 \). Find the values of \( a \) and \( b \). c Show that the equation of the tangent to \( y=2 x^{2}-1 \) at the point where \( x=a \), is \( 4 a x-y=2 a^{2}+1 \).
