Answer:

The area of the trapezoid is 238 m^2.

Step-by-step explanation:

The formula to use in order to calculate the area of a trapezoid is \frac{h}{2}(b_{1} +b_{2}) where b_{1} and b_{2} are the lengths of the top and bottom bases of the trapezoid, and h is the height of the trapezoid. In this case, we can rewrite the formula by inserting the corresponding values into the expression. The area of the trapezoid will be \frac{14}{2} (15+19)=7*34=238m^2.

Find the total number of dogs by adding each day:

Total dogs = 23

Percent of dogs: Divide the number of dogs by the total number of patients:

= 23 / 50 = 0.46 x 100 = 46%

Use the given formula to find the standard error:

Standard error = √(0.46*(1-0.46)/50) = 0.07

90%: Find Z value for 90% ( 1.645) multiply by SE:

1.645 x 0.07 = 0.115 = 0.12

Now add and subtract that value from the Percent from above:

46 + 12 = 58%

46-12 = 34%

Answer (34%, 58%)

95%: Find Z value for 95% ( 1.96) multiply by SE:

1.96 x 0.07 = 0.137 = 0.14

Now add and subtract that value from the Percent from above:

46 + 14 = 60%

46-14 = 32%

Answer (32%, 60%)
