A quantitative data set has mean 23 and standard deviation 2. At least what percentage of the observations lie between 15 and 31? At least nothing% of the observations lie between 15 and 31.

Atleast 93.75% of data lies between 15 and 31.

Step-by-step explanation:

We are given the following in the question:

Mean = 23

Standard deviation = 2

We have to find he data lying between 15 and 31.

Thus, we have to find the data lying within 4 standard deviation from the mean.

Chebyshev's Theorem:

Thus, atleast 93.75% of data lies between 15 and 31.

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
