Researchers found that the constant exposure to mass media (television, magazines, websites) depicting atypically thin, glamorous female models (the thin-ideal body) may be linked to body image disturbance in women. The general hypothesis was that the more women were exposed to pictures and articles about thin females perceived as ideal, the lower their satisfaction was with their own bodies. The researchers collected data to test this hypothesis. The data is given below.

Test the hypothesis at the 5% significance level (? = 0.05) using the 5-step hypothesis testing procedure (show ALL steps). Make sure to clearly state the null and alternative hypotheses in formal symbol notation (or in words if formal symbol notation is not appropriate). Show your work. Show the formula and all steps of the calculations and not just the final answer. Round all values to 2 decimal places.
