Answer:

a) 2.0702

b) 2.07

Step-by-step explanation:

Given:

Sample, n = 840

standard deviation, σ = 60

a) The standard deviation of the sampling distribution, will be:

= \frac{\sigma}{\sqrt{n}}

= \frac{60}{\sqrt{840}}

= 2.0702

Standard deviation of the sampling distribution is 2.0702

b) According to the 68 part of the 68-95-99.7 rule, 68% of all values of x fall within 1 standard deviation on either side of the unknown mean μ.

Therefore, missing number will be:

1 * [\frac{\sigma}{\sqrt{n}}]

= 1 * 2.0702

= 2.0702 ≈ 2.07
