Question

a. among the 515 human resource professionals who were surveyed, how many of them said that body piercings and tattoos were big personal grooming red flags?
(round to the nearest integer as needed.)

Explanation:

Step1: Calculate the number

We know that the total number of professionals is \(n = 515\) and the proportion \(p=45.8\%=0.458\). The number of professionals who said body piercings and tattoos were big personal grooming red - flags is \(N=n\times p\).

$$N = 515\times0.458$$

Step2: Compute the product

$$515\times0.458=(500 + 15)\times0.458=500\times0.458+15\times0.458$$

$$500\times0.458 = 229$$

, \(15\times0.458=6.87\)

$$N=229 + 6.87=235.87$$

Step3: Round to the nearest integer

Since \(235.87\approx236\) (rounding to the nearest integer)

Answer:

236
