Should you be confident in applying your regression equation to estimate the heart rate of a python at 35°C? Why or why not?

Given your fitted regression line, what would be the residual for snake #5 (10 C)?

Calculate the 95% confidence interval around your estimate of r using Fisher’s z-transformation. In your final answer, make sure to back-transform to the original units.

Calculate Pearson’s correlation coefficient (r) between temperature and heart rate.

Calculate the least squares regression line and write the equation.

Test the null hypothesis that the slope is zero (e.g., β=0).

Do College Students With Part-Time Jobs Sleep Less? College students were surveyed about the number of hours they sleep each night.Group A = With part-time jobs | Group B = Without jobs Group A: 6, 5, 7, 6, 5Group B: 8, 7, 9, 8, 7 Instructions: State your hypothesis and perform a two-sample t-test with all formulas. Create histograms for each group. Label axes and add titles. Comment on the distribution shape (e.g., normal, skewed, etc.).Solve on pen and paper
