Question
What percentage of the area under the normal curve lies(a) to the right of $\mu ?$(b) between $\mu-2 \sigma$ and $\mu+2 \sigma ?$(c) to the right of $\mu+3 \sigma ?$
Step 1
The normal distribution is symmetric about its mean, denoted as \(\mu\), and its spread is determined by the standard deviation, \(\sigma\). The total area under the normal curve is 1, which corresponds to 100%. Show more…
