A manufacturing firm finds that 80% of its new hires turn out to be good workers and 20% become poor workers. All current workers are given a reasoning test. Of the good workers, 90% pass it; 30% of the poor workers pass it. Assume that these figures will hold true in the future. If the company makes the test part of its hiring procedure and only hires people who meet the previous requirements and also pass the test, what percent of the new hires will turn out to be good workers?

A reporter for a local television station visits the city's new upscale shopping mall the day before Christmas to interview shoppers. He questions the first 25 shoppers he meets outside one of department stores at the mall. He asks them whether their overall feelings about Christmas shopping are positive, neutral, or negative. Select the reason(s) why it may be risky to act as if the first 25 shoppers at this particular location are an SRS of all shoppers in the city. Surveying shoppers the day before Christmas is a convenience sample, so it is a simple random sample. Shoppers at the mall the day before Christmas does not guarantee every shopper in the population has an equal chance to be in the sample. Surveying shoppers at the mall the day after Christmas may not be a good represenation of all shoppers in the city. Having the reporter ask questions is not a double‑blind study.
A teacher was listening to some of her students talk about how many SnapChats they send during the day. The teacher decided that she wanted to conduct a study to see if the number of SnapChats a student sends per day affects how much time students talk to their friends face-to-face.

Then, the teacher had students record how many conversations they had with their friends during the week, gathered the data, and analyzed the results. What type of study is this? Experimental or observational?
