The degrees of freedom for calculating the value of t are:
With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.
The sample size to get a margin of error equal or less than 0.3656 can be calculated as:
Answer:
Step-by-step explanation:
The shape above is a composite shape having two different shapes like rectangle and semi- circle
Area of rectangle=Length × Breadth
Area of semi circle=1/2πr^2
To find the area of the rectangle naw
Length of the rectangle=6.6
Width of the rectangle=4
A=6.6×4
A=26cm^2
Area of semi-circle=1/2
Diameter of the shape =4cm
Radius=2cm
A=1/2×3.14×2cm x2cm
A=6.28cm^2
Area of the shape=26+6.28cm^2
Area=32.28 to 2 dp
