Integra learning systems is a private company that believes it can increase a child's IQ by giving them videos to watch, specific kinds of games to play, and by emphasizing a gluten free diet. Through these activities, the program insists that children are becoming smarter. They stress that smarter children leads to better learners, higher grades, and higher incomes as adults. A researcher wants to compare children that have been in this program to the general population. The researcher locates 10 such children with a mean IQ of 114. Are they different than the population? (For this example, IQ scores distribute normally with a mean of 100 and a SD of 15.) Z = X-μ ox (Write your answer in the box) B. We will use a two-tailed test. 0x = A. Wow, mean IQ of 114. These kids look smart. On the other hand, this could all be due to: 1. H₂: X = ø 2. H₁: X Ø # 3. Ho: μ = Ø 4. Ho: X = μ 5. H₁: Xu 6. Ho: X = μ Enter the number of the expression indicating the null hypothesis into this box: P √n 2 a 6 55

For 25 years, Arthur Reynolds and Judy Temple tracked more than 1,400 children who participated in a publicly funded early childhood development program beginning at age 3. They found that children who participated in the program showed higher levels of educational attainment, socioeconomic status, and job skills, as well as lower rates of substance abuse, felony arrest, and incarceration, than those who did not receive school-based early education. One possible theory for the success of this program is that improving school readiness improved the children's success in school. The improved success in school in turn improved their readiness for adulthood, resulting in increased job skills and socioeconomic status as well as lower rates of substance abuse.
Social media provides an enormous amount of data about the activities and habits of people using social platforms like Face book and Twitter. The belief is that mining that data provides a treasure trove for those who seek to quantify and predict future human behavior. A marketer is planning a survey of Internet users in the United States to determine social media usage. The objective of the survey is to gain insight on these three items: key social media platforms used, frequency of social media usage, and demographics of key social media platform users. a. For each of the three items listed, indicate whether the variables are categorical or numerical. If a variable is numerical, is it dis crete or continuous? b. Develop five categorical questions for the survey. c. Develop five numerical questions for the survey.
