Chapter 17, Problem 20P
- Cialdini, Reno, andKallgre,n (11990) examined how peo ple conform to norms concerning liner mg. The research
er wanted to determine whether a person ' tendency to litter depended on the amount of litter already in the area. People were handed a handbill as they entered an amusement park. The entrance area had already been prepared with either no litter, a small amount of litter or a lot of litter lying on the ground. The people were
observed to determine whether they dropped their hand bills The frequency data are as follows:
Littering
Amount of Litter Small
Large
None
Amount
Amount
- Do the data indicate that people’s tendency 1to litter depends on the amount of litter already on the ground? That is, is there a significant relationship between littering and the amount of existing litter? Test at the .05 level of significance.

A European football agency reports the following based on a study they did: 90% of soccer players take magnesium in topical form for muscle soreness, 5.5% take magnesium in pill form, and 4.5% take magnesium in powder form. To verify, a researcher randomly selects 794 soccer players and reports the following.

To determine if the proportions the European football agency reported are accurate, the researcher will conduct a Chi-square Goodness of Fit test. Complete the table below to calculate the chi-square statistic. Round all values to two decimal places! (Use the correct expected counts from the previous question.)
