Question 1 Not answered Marked out of 2.00 Flag question Have a look at the following coefficient table from a regression model. The DV is depression. 'anx' is attachment-anxiety, and 'avoid' is attachment-avoidance. For all variables, higher scores represent greater levels of depression/attachment. dep Coefficient Std. err. t P>|t| [95% conf. interval] anx avoid _cons 3.015268 .3385391 1.697327 .3398616 11.50801 1.563327 8.91 4.99 7.36 0.000 0.0004 0.000 2.348944 1.0284 8.431013 3.681593 2.366255 14.585 In APA format, write a 1-2 sentence summary of these results.

Find the equation of the regression line for the following data set. x 1 2 3 y 0 3 4

Respiratory Rate Researchers have found that the 95 th percentile the value at which 95% of the data are at or below for respiratory rates in breath per minute during the first 3 years of infancy are given by y=101.82411-0.0125995x+0.00013401x2 for awake infants and y=101.72858-0.0139928x+0.00017646x2 for sleeping infants, where x is the age in months. Source: Pediatrics. a. What is the domain for each function? b. For each respiratory rate, is the rate decreasing or increasing over the first 3 years of life? Hint: Is the graph of the quadratic in the exponent opening upward or downward? Where is the vertex? c. Verify your answer to part b using a graphing calculator. d. For a 1- year-old infant in the 95 th percentile, how much higher is the walking respiratory rate then the sleeping respiratory rate? e. f.

For the following exercises, use Table 4 which shows the percent of unemployed persons 25 years or older who are college graduates in a particular city, by year. Based on the set of data given in Table 5, calculate the regression line using a calculator or other technology tool, and determine the correlation coefficient. Round to three decimal places of accuracy
