Quizplus · Accepted Answer

We need to find the z-score corresponding to a probability of 0.1093 in the right tail. Using z-tables or a calculator, we find that the z-score corresponding to this probability is approximately 1.23. Therefore, c = -1.23 (since we're looking for the probability to the right of c, which is negative). Option D is the correct choice.

Solve the Problem P(z>c)=0.1093\mathrm { P } ( \mathrm { z } > \mathrm { c } ) = 0.1093P(z>c)=0.1093

Solve the Problem $\mathrm { P } ( \mathrm { z } > \mathrm { c } ) = 0.1093$
