A researcher wanted to include an advertisement on a web page, but only if the advertisement was one that people found attractive. A sample of 5 people were asked to rate the photograph on a 7-point scale ranging from 1 (Very Unattractive) to 7 (Very Attractive). The researcher was willing to include the advertisement if the scores on the pretest were significantly greater than 4 (the mid-point on the scale). Would the researcher include the photograph? Conduct a 1-sample t-test on the scores below and report whether or not the researcher would use the photograph.

A sample of n 12 males looks at a set of 30 photographs of women and rates the attractiveness of each woman using a 5-point scale (5 most positive. One photograph appears...

Calculations: Background and Data A researcher wanted to know if the color of a room would affect the perceived attractiveness of another person. She recruited 18 participants and divided them into three groups where each group would correspond to a differently colored room (Yellow, Green, & White). Each participant was asked to sit in the room and have a five minute conversation with a research confederate thought to be another participant. Afterwards they were asked to rate the attractiveness of...

Question 1A researcher interested in the effects of alcohol on fine motor control randomly assigned 12 participants to one of three groups. Participants consumed either 0,5, or 15 ounces of alcohol. They traced a star while looking at the image of the star in a mirror. The researcher counted the number of errors each participant made while performing the mirror image tracing task. Conduct a one-way ANOVA on the following data to determine if alcohol affected performance. You need to...

The main difference between single sample t-testing and related sample t-testing is the focus on "D" or difference scores. T or F There is some evidence indicating women who have visible tattoos are viewed as less attractive than people who have no visible tattoos. To test this hypothesis a researcher will provide a sample of participants a photo of 5 women before she obtained a tattoo then again after a computer generated tattoo is placed on her skin. The researcher...

2. (17 pts total) Research has shown that people find symmetrical faces more attractive than faces that are not symmetrical. For example, a psychologist selected a random sample of 12 people and used random assignment to place them in 1 of 3 conditions. Depending on their condition assignment, participants were shown one of three pictures: a face that is perfectly symmetrical, a face that is slightly asymmetrical, and a face that is highly asymmetrical. The researcher then...

In a condition of an experiment (based on a sample), a researcher obtains the following creativity scores: 3 2 1 0 7 4 8 6 6 4 In terms of creativity, interpret the variability of these data using the standard deviation. Assume that the sample has an N of 1000. By making use of the method of standardization, about how many people would you expect to score below 1.59?
