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

Find all numbers whose absolute value is – 3.

Gwar [14]

Answer:

remember that $|x|=x$ if $x\geq0$ and $|x|=-x \; \text{ if } x\leq 0$ . This means that $|x|$ always is a positive number.

Then, there are no numbers such that $|x|=-3$ because -3 is a negative number.
