Question 13 of 25 To test whether a special soap works as advertised, Bob has 5 people wash their hands with the soap and 5 people wash their hands with regular soap. The people who washed with the special soap have cleaner hands, so Bob says that the soap works. What is Bob doing? A. Making an inference B. Gathering data C. Drawing a conclusion D. Making a hypothesis

2. Use the list of data to make a box plot what is the tgis? \[ 5,8,1,3,5,11,5,8,4 \]

I In your own words, what is mean absolute deviation and how do we calculate it?

Based on historical data at Oxnard college, they believe that \( 42 \% \) of freshmen do not visit their advisors regularly. For this year, you would like to obtain a new sample to estimate the proportion of freshmen who do not visit their advisors regularly. You would like to be \( 90 \% \) confident with a margin of error of \( 4 \% \). Assume the conditions are met and use the appropriate formula to determine how many people you would need to sample. \( n=412 \) Show your steps on paper or in the add work box: Question Help:

Out of 500 households sampled, 190 had kids under 18 living at home. Assuming the conditions are met, use the theoretical formula to construct a(n) \( 90 \% \) confidence interval for the true population proportion of households with kids under 18 living at home. a. Give your theoretical confidence interval in decimal form. Use 4 decimal places in your calculations and round your answers to four decimal places. ( \( 0.334,0.415 \) ) b. Interpret the confidence interval in context: We are \( 90 \% \) confident that the proportion of households with kids Show your formula and steps on paper or in the add work box (don't skip the between \( 34.43 \% \) and \( 41.57 \% \). interpretation above):

Why does it help to organize data in a table? A. It helps you pick a responding variable. B. It helps you determine a relationship between variables. C. It helps you erase the data that do not fit the claim. D. It helps you form a hypothesis.
