Tcecarenko [31]
Since we do not know the population standard deviation, we will use the t-distribution to construct the 90% confidence interval of the mean number of books people read. The value of t_{\frac{\alpha }{2}} with 1010 degrees of freedom and with alpha equals to 0.10 is 1.64

First, we need to solve for the margin of error, E.
     E=t_{\frac{\alpha }{2}}\cdot \frac{s}{\sqrt{n}}=1.64\cdot \frac{16.6}{\sqrt{1011}}=0.86

The lower bound of the confidence interval is 
     LB=\overline{x}-E=14.8-0.86=13.94

The upper bound of the confidence interval is 
     LB=\overline{x}+E=14.8+0.86=15.66

Therefore, the 90% confidence interval is (13.94, 15.66).

We are 90% confident that the interval from 13.94 books to 15.66 books does contain the true value of the population mean number of books people read.

The car is traveling up a steep ramp to a parking garage. The ramp is 445 feet long and rises a vertical distance of 80 feet. Wh
Olin [163]
The ramp is modelled as shown in the diagram below.

The angle of elevation from the car is the angle form by the horizontal line and the observer eye from the car. In the diagram, this angle is marked by x

We use trigonometry ratio to work out the value of x

tan(x)= \frac{opposite}{adjacent}
tan(x)= \frac{80}{445}
x= tan^{-1}( \frac{80}{445})
x=10.19°
