Question
9. 64% media influence your attitude toward tanning? D0 taologists' primary recommendation to prevent skin Dermiz is minimal exposure to the sun. Yet, models used duct advertisements are typically well tanned. Do rtisements influence a consumer's attitude to- ning? University of California and California State researchers designed an experiment to investi- onte this phenomenon and published their results in Basic and Applied Social Psychology (May 2010). College student articipants were randomly assigned to one of three condi- tions: (1) view product advertisements featuring models with a tan, (2) view product advertisements featuring mod- els without a tan, or (3) view products advertised with no models (control group). The objective was to determine whether the mean attitude toward tanning differs across the three conditions. A tanning attitude index (measured on a Universit niversity scale of 0 to 5 points) was recorded for each participant. The results are summarized in the accompanying table.

Mahler et al., "Effects of Media Images on es Toward Tanning," Basic and Applied Social Psychology Vol.32, No. 2, May 2010 (adapted from Table 1).Explanation / Answer
A.
c. A null hypothesis where there is no statistical significance between two variable. It is usually the hypothesis which is to be disproved by the researcher.
An alternative hypothesis is one that states there is a statistical significant relationship between two variables.
D.
The statistic called p value approach to be used. It involves determining likely or unlikely by determining the probability-assuming the null hypothesis were true of observing a more exctreme test stayistic in the direction of the slternative hypothesisyhen the one observed.
If P value is smaller then or equal to alpha. Then it is unlikely then reject null hypothesis and if greater then alpha then the null hypothesis is not rejected.
