MAT 258 Lab 5 Due Monday April 25th (4/25/2022) by 2:50pm For this lab you are to address each of the following parts in a lab write-up. Include any relevant Minitab output into your lab write-up. The write-up should be well organized and clearly indicate which part of the lab the submitted response is addressing. The Lab assignment will be collected through Blackboard as a word file or as a pdf and can be found in the content folder labeled Lab 5. Consider an investigator is interested in determining if a linear relationship exists between the amount of sunlight exposure (days) a certain species of plant has, and the growth of the plant (millimeters) at a=0.05 significance level. Where growth is the response variable, and sunlight is the explanatory variable. They collect a random sample of 25 plants of a certain species and measure the amount of sunlight exposer and change in growth over a certain period of time.

Include the mean, median, standard deviation, maximum value, and minimum value. b) Write out the statistical hypotheses of interest for the slope of the least-squares regression model in this scenario. c) Verify that the normality assumption is met for this regression model. d) Provide the p-value for the hypothesis test of interest in this experiment, and the conclusion that you would make for this experiment. e) Produce the 95% confidence interval for the true slope coefficient of the least-squares regression line in Minitab. f) Using the formula from class calculate a 95% confidence interval for the true slope coefficient of the least-squares regression line. g) Produce a 90% confidence interval for the mean growth of plants that have had 21.3 days of sun exposure. h) Provide an interpretation of the confidence interval produced in part g.
