Answer #1

(a)

By Empirical Rule:

68% of data will lie in mean Standard deviation

= 360 14 = (346, 374)

So,

Answer is:

Value 1 346
Value 2 374

(b)

By Empirical Rule:

95% of data will lie in mean 2 X Standard deviation

= 360 ( 2 X 14) = 360 28 = (332, 388)

So,

Answer is:

Value 1 332
Value 2 388

(c)

By Empirical Rule:

Practically all of observations will lie in mean 3 X Standard deviation

= 360 ( 3 X 14) = 360 42 = (318, 402)

So,

Answer is:

Value 1 318
Value 2 402
