4. A large company wants to find the favorite animal of their employees…would surveying every 5th women who uses the copier, be a random, representative sample? explain your answer.
5. 50 students are randomly selected and 4 own cats. If there are 800 students, how many of them own cats?
4. Surveying every 5th woman who uses the copier may not result in a random, representative sample of the company's employees' favorite animals. This method may not capture a diverse range of responses as it only targets a specific subset of the population (women who use the copier). It could potentially introduce bias as certain groups of employees may be overrepresented or underrepresented in the sample.
5. If 4 out of 50 students own cats, then the proportion of students who own cats in the sample is 4/50 = 0.08. If we assume that this proportion holds true for the entire population of 800 students, then the estimated number of students who own cats would be 0.08 x 800 = 64 students. So, it can be estimated that 64 out of 800 students own cats.
