To use the tree house as the start of the zip line, the cable needs to be attached to the starting tree at a height 16 feet above the ground.
To meet the slope constraint, Vince wants to change the height 7 feet and
end the zip line at a height 9 feet above the ground. He claims this vertical
change meets the slope constraint.
Test Vince's claim for Tree A and Tree B. Use specific numbers from the
situation to justify or refute whether having a vertical change of 7 feet will
satisfy the slope constraint for each tree.

Arandomized controlled trial is designed to evaluate the effect of metoprolol in patients with heart failure. while preparing for statistical analysis, the researcher reviews some common types of statistical errors. which of the following statements is true regarding a type i error in a clinical study? a. the study is not significantly powered to detect a true difference between study groups. bthe null hypothesis is true but is rejected in error. c. the null hypothesis is false but is accepted in error. d. type i error is also known as beta and is usually 0.1 or 0.2. e. type i error depends on the study's confidence interval.
