Question

now, compute $mu - 3sigma$ and $mu + 3sigma$, given that $mu = 350$ and $sigma = 7$.
$mu - 3sigma=350 - 3(quad)
=quad
mu + 3sigma=quad+3(7)
=quad
therefore, a 75% chebyshevs interval around the sample mean is the following. (enter your answer in the form: lower limit to upper limit. include the word to.)
(quad)$

Explanation:

Step1: Calculate $\mu - 3\sigma$

Substitute $\mu = 350$ and $\sigma=7$ into $\mu - 3\sigma$.
$350-3\times7=350 - 21=329$

Step2: Calculate $\mu + 3\sigma$

Substitute $\mu = 350$ and $\sigma = 7$ into $\mu+3\sigma$.
$350 + 3\times7=350+21 = 371$

Answer:

329 to 371
