Let X be normally distributed with mean mu = 4.6 and standard deviation sigma = 2.4 Find P(X > 6.5).
Added by Kelly C.
Step 1
5 by converting it to a z-score using the formula: \[ z = \frac{X - \mu}{\sigma} \] Plugging in the values, we get: \[ z = \frac{6.5 - 4.6}{2.4} = \frac{1.9}{2.4} \approx 0.79 \] Show more…
