Question

now, compute $\bar{x}-2s$ and $\bar{x} + 2s$, given that $\bar{x}=45$ and $s = 9$.
$\bar{x}-2s=45 - 2(quad)$
$=quad$
$\bar{x}+2s=quad+2(9)$
$=quad$
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.\)

Explanation:

Step1: Substitute s value for x - 2s

$45-2\times9$

Step2: Calculate x - 2s

$45 - 18=27$

Step3: Substitute s value for x + 2s

$45+2\times9$

Step4: Calculate x + 2s

$45 + 18=63$

Answer:

27 to 63
