Area of a circle is PI x r^2:
Area of circle = 3.14 x 13^2 = 530.66 square meters.
To find the area of the sector multiply the area of the circle by the fraction of the sector
Area of sector = 530.66 x 150/360 = 221.108 square meters ( Round the answer as needed).
We' supposed to indicate which statement is true/false.
Note that, if a sample size is 40 or over, we can use the t distribution even with skewed data. So it's not highly sensitive to non-normality of the population from which samples are taken. So statement A is false.
It's true that the t-distribution assumes that the population from which samples are drawn is normally distributed. So B is true.
For skewed data or with extreme outliers, we can't use the t distribution. We only use t distribution as long as we believe that the population from which samples are drawn is closed to a bell-shape. So C is true.
Lastly, statement D is against statement C. So D is false.
