The variance of the scores on a skill evaluation test is 143,641 with a mean of 1517 points. If 343 tests are sampled, what is t

Vlad1618 [11]

Answer:

The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

Step-by-step explanation:

We are given that

The variance of the scores on a skill evaluation test=143,641

Mean=1517 points

n=343

We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.

Standard deviation, $\sigma=\sqrt{143641}$

$P(|x-\mu|$

$=P(|Z|$

$=0.9216$

Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216

Ganezh [65]

Answer: I think it is 4 places to the left.

Step-by-step explanation: Usually when dividing numbers like 1000, 100, etc. with decimals, I count the amount of zeros and then move the decimal point to the left the amount of zeros there are. When you multiply you move the decimal to the right, when you divide you move the decimal to the left.
