A dendritic tree is a branched structure that emanates from the body of a nerve cell. As part of a study of brain development, 36 nerve cells were taken from the brains of newborn guinea pigs. The investigators counted the number of dendritic branch segments emanating from each nerve cell. The numbers were as follows:

The psychologist is interested in how nutritious breakfast and sugary breakfast plays a role in growth. Each kindergartner was randomly assigned to one of two groups. In one group, the child was provided with a well-balanced breakfast including yogurt, fruit and oats, while the second group of children were provided with sugary cereals, muffins, and juice. The independent variable is ______________________ This is a (true or quasi) independent variable ____________________ This independent variable has __________ levels The dependent variable is ___________________ If the researcher used a graph to show the obtained relationship between the independent variable and dependent variable, what kind of graph would be appropriate? __________________________________________arrow_forwardA psychologist is interested in constructing a 99% confidence interval for the proportion of people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain. 68 of the 754 randomly selected people who were surveyed agreed with this theory. a. With 99% confidence the proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain is between ___ and ___. b. If many groups of 754 randomly selected people are surveyed, then a different confidence interval would be produced from each group. About____ percent of these confidence intervals will contain the true population proportion of all people who accept the theory that a person's spirit is no more than the complicated network of neurons in the brain and about____ percent will not contain the true population proportion.arrow_forward
