The results showed that 2,973 out of 4,135 respondents are worried about a future in which robots and computers can do many human jobs; 2,774are worried about the development of algorithms that can evaluate and hire job candidates; and 2,236 are worried about the development of driverless vehicles. (Round your answers to four decimal places.)

(a)

Develop a point estimate of the proportion of respondents who are worried about a future in which robots and computer can do many human jobs.

(b)

Develop a point estimate of the proportion of respondents who are worried that the development of algorithms that can evaluate and hire job candidates.

(c)

Develop a point estimate of the proportion of respondents who are worried about the development of driverless vehicles.

Answer 1

Using the sample proportion concept, it is found that the point estimates are given by:

a) 0.719.

b) 0.6709.

c) 0.5407.

What is a sample proportion?

A sample proportion is given by the number of desired outcomes divided by the number of total outcomes. It is also the point estimate of the population mean.

Item a:

Out of the 4135 residents, 2973 are worried about a future in which robots and computers can do many human jobs, hence, the estimate is:

p = 2973/4135 = 0.719.

Item b:

2774 out of 4135, hence:

p = 2774/4135 = 0.6709.

Item c:

2236 out of 4135, hence:

p = 2236/4135 = 0.5407.
