he pulse rates of 179 randomly selected adult males vary from a low of 43 bpm to a high of 115 bpm. Find the minimum sample size

malfutka [58]

Answer:

Step-by-step explanation:

Given that:

Low = 43bpm

High = 115 bpm

Error = 3

α = 90%

To find the range estimate :

Standard destviation = (high - low) / 4

Standard deviation = (115 - 43) / 4

Standard deviation = 72/4 = 18

The sample size,(n) :

n = [(Zα/2 * sd)/E] ²

2 - tail = (Zα/2) = 1.645

[(Zα/2 * sd)/E] ² = [(1.645 * 18) / 3]² = (29.61/3)²

= 97.41

Sample size = 97

Use the Associative Property of Addition to write an expression equivalent to (n + 2) + 7. Which expression is equivalent to (n

insens350 [35]

Answer:

The correct answer is OB.

Step-by-step explanation:

Let us recall the Associative Property of Addition: given three real numbers $a$ , $b$ and $c$ the following equality holds:

$(a+b) + c = a+(b+c)$ .

Let us remark that the Associative Property of Addition tells us that we can perform the sums in any order. So,

$(n+2)+7 = n+(2+7)$ .

In the other options there was used the Commutative Property of Addition.
