Question

what is the mean of the dataset in the normal model ( n(870, 135) )? (1 point)
mean = \square

Explanation:

Step1: Recall normal model notation

The normal model $N(\mu, \sigma^2)$ uses $\mu$ (first value) for mean.

Step2: Identify mean from given model

Given $N(870, 135)$, the first value is 870.
