Twenty-nine college students, identified as having a positive attitude about Mitt Romney as compared to Barack Obama in the 2012 presidential election, were asked to rate how trustworthy the face of Mitt Romney appeared, as represented in their mental image of Mitt Romney’s face. Ratings were on a scale of 0 to 7, with 0 being “not at all trustworthy” and 7 being “extremely trustworthy.” Here are the 29 ratings: 2.6 3.2 3.7 3.3 3.4 3.6 3.7 3.8 3.9 4.1 4.2 4.9 5.7 4.2 3.9 3.2 4.5 5.0 5.0 4.6 4.6 3.9 3.9 5.3 2.8 2.6 3.0 3.3 3.7 a 95% confidence interval for the mean rating. Is there significant evidence at the 5% level that the mean rating is greater than 3.5 (a neutral rating)?

"Bluth's Original Frozen Banana Stand" is a frozen banana stand founded in 1953 by George Bluth. They offer multiple types of chocolate that you can have your frozen banana dipped in, and they also offer multiple different toppings for your frozen banana. One day when stand employee Michael was working, he wondered whether or not there was a relationship between what customers had their bananas dipped in (milk chocolate, white chocolate, or dark chocolate) and their choice of topping (plain, walnuts, or sprinkles). He recorded the choices of each for 90 different customers, and the resulting data can be seen in the table below. Which cell has the highest Chi Square contribution?

Hello, I was told to repost again for the multiple choice question for the Two Way Frequency table. Thank you in advance!
490 undergraduate students at a state university in the southwestern region of the United States were surveyed. Each student in the sample was classified according to class standing (freshman, sophomore, junior, or senior) and body are category (body piercings only, tattoos only, both tattoos and body piercings, no body art). Use the data in the accompanying table to determine if there is an association between class standing and body art category. Assume that it is reasonable to regard the sample as representative of the students at this university. Use α = 0.01. 1. What type of question is this-estimation or hypothesis?2. What type of study is this sample data or experiment data?3. What type of data is this? Univariate or bivariate? Categorical or Numerical?4. How many samples or treatments?
The ANOVA test described shows whether or not there is a a. Relationship b. Preference C. Dependence d. Equality of three or more means e. None of these
Assume that 135 surveys are completed. Of those surveyed, 61 responded positively to effectiveness, 65 responded positively to side effects, and 63 responded positively to cost. Also, 26 responded positively to both effectiveness and side effects, 29 to effectiveness and cost, 26 to side effects and cost, and 16 to none of the items. How many responded positively to all three?
