Although consumers often want to touch products before purchasing them, they generally prefer that others have not touched products they would like to buy. Can another person touching a product create a positive reaction? Subjects were given instructions to contact a sales associate at a university bookstore who would provide them with a shirt to try on. When meeting the sales associate, subjects were told that there was only one shirt left and it was being tried on by another “customer.” The other customer trying on the shirt was a confederate of the experimenter and was either an attractive, well-dressed professional female model or an average-looking female college student wearing jeans and a tee shirt. Subjects, who were either males or females, saw the confederate leaving the dressing room, where the shirt was left for them to try on. There was also a control group of subjects who were handed the shirt directly off the rack by the sales associate. Thus, there were five treatments:…

In an imaginary survey, we wanted to find out if there is a connection between morning sickness and sleeping position. A random sample of 400 people was selected for the survey. The respondent had to define himself as either a morning person or a non-morning person and tell the position in which he typically sleeps.186 respondents classified themselves as morning timers and 214 respondents as non-morning timers.Of the morning owls, 127 reported that they usually sleep on their side, 24 on their stomach and 35 on their back.Of the non-morning people, 156 reported that they usually sleep on their side, 29 on their stomach and 29 on their back.Use the chisq.test() function to test the null hypothesis that there is no connection between morning knitting and sleeping position. What is the p-value? Give the answer to four decimal places. Remember the correct decimal separator.
In Jolie’s new Thai restaurant, she observes the age of her customers and notes down which of the groups they belong to – ’18 years old and below’ or ‘above 18 years old’, and whether they spent more than $30 on a single meal - ‘big spender’ or ‘non-big spender’. Given that rate (big spender | above 18 years old) > rate (big spender | 18 years old and below), what conclusion can be made? a) Being a big spender and being above 18 years old are negatively associated.b) Being a big spender and being above 18 years old are positively associated.c) Being above 18 years old is positively associated with visiting her restaurant.d) Being above 18 years old causes one to become a big spender.

The majority of clothing retailers use mannequins to display their merchandise, with approximately one‑third displaying mannequins with heads and two‑thirds displaying mannequins without heads. Researchers recruited 126 female participants and assigned each to one of the two mannequin styles (head/headless). Participants were asked to imagine that they wanted to buy a new dress and told to go to a named store to make their purchase. They then viewed the dress displayed on a mannequin (head or headless) and were asked whether or not they would buy the dress. Of the 63 participants viewing the dress displayed on a mannequin with a head, 18 indicated that they would buy the dress, while only 10 of the 63 participants viewing the headless mannequin indicated that they would buy the dress. Assuming the conditions are met, calculate the test statistic and ?-value. Give the test statistic to two decimal places and ?-value to four decimal places.
