Be sure to include T statistic (t) and (F) **Consider the values for the dependent and independent variables shown:**| x | y ||---|---|| 5 | 10 || 15 | 13 || 40 | 25 || 50 | 44 || 60 | 78 || 80 | 113 |a. **Develop a scatter plot of the data.** Does the plot suggest a linear or nonlinear relationship between the dependent and independent variables?b. **Develop an estimated linear regression equation for the data.** Is the relationship significant? Test at an α = 0.05 level.c. **Develop a regression equation of the form** \( \hat{y} = b_0 + b_1x + b_2x^2 \). Does this equation provide a better fit to the data than that found in part b?

Assume that a high school principal believes that high number of absences hinders the students' ability to perform on standardized tests. He randomly selects a sample of 9 students who had 5 or more absences in the school year. The average ACT Composite score for this sample is X = 19 with s = 4.9. ACT Composite scores are normally distributed with u = 21.0. Do the data support the claim that the high number of absences hinders the students' ability to perform on standardized tests, using a = .05? Please show the four-step hypothesis test. %3D
