A firm has determined, from past experience, that the learning curve for a new electronic component has a log$-$linear form with a slope coefficient $(n)$ of $-0\mathrm{.}10.$ In this case s$,$ which is the learning curve slope parameter expressed as a decimal, equals

a$.0\mathrm{.}933$

b$.$ We need more information to answer this question.

c$.$ Greater than $0\mathrm{.}74$ but less than $0\mathrm{.}933$

d$.0\mathrm{.}74$
