The height of an object can be measured using trigonometry. • H = x tanθ + h • H is the height of the object • x is the distance from the base of the object to a fixed point • θ is the angle of elevation from the fixed point to the top of the object • h is the height of the platform
H0 :=360 (null hypothesis) • The null hypothesis is assumed true until sufficient evidence is obtained to warrant its rejection. • Ha :360 (alternative hypothesis) • The alternative hypothesis is accepted as true if we can disprove the null hypothesis.
To get the most accurate measurement of the height of Brownlee Hall
Tape Measure • Angle Measurer (protractor) • Orange Cone • Calculator
We measured the distance from the object in inches . • We measured the angle of elevation in degrees. • We measured the height of the platform in inches.
We calculated the tangent of the angle of elevation. • We then multiplied the distance from the object by the calculated tangent of the angle of elevation. • The height of the platform was then added to the product of the distance from the object and the calculated tangent of the angle of elevation.
Because the p value was so low our null hypothesis is rejected. • The data we collected for the height of the building was not accurate. • Therefore, the alternative hypothesis is accepted.
However, in doing this research we did learn how to form and test a null and alternative hypothesis and to make a conclusion from the data collected. • The height of an object is equal to the distance from the object multiplied by the tangent of the angle of elevation; this product is added to the height of the platform for the final answer.
