The demand function below is estimated using the data generated by a randomized controlled trial:

Lnq_x^d=a+b*Lnp_x+c*Lnp_Y+d*Lnp_z+e

where q_x^dis the quantity demanded of the product of interest (X), p_xis the price of the product of interest (X), p_yis the price of a substitute product (Y), and p_zis the price of a complement product (Z). Also, e is the error term. The table below shows the 95% confidence interval estimation for parameters b, c, and d:

Parameter	Lower Limit of 95%CIE	Upper Limit of 95%CIE
b	-0.052	-0.031
c	-0.025	+0.045
d	-0.154	-0.075

16. Consider thelowerlimit of 95%CIE for parameter b. A 10 percent increase in price of X is expected to reduce the demand for X by _____ percent.

Note: Round your answer to two decimal points.

17. Consider theupperlimit of 95%CIE for parameter b. A 10 percent increase in price of X is expected to reduce the demand for X by _____ percent.

Note: Round your answer to two decimal points.

I tried it and answers are not 5.2% and 3.1%

any help?
