sineoko [7]

Answer:

78386.96 Square Yards

Step-by-step explanation:

Circumference of the Widest Circle of the Sphere=496.12 yd

Therefore:

$2\pi r =496.12 \:yards\\2*3.14*r=496.12\\r=496.12\div(2*3.14)\\r=79 yd$

Surface Area of the Sphere = $4\pi r^2$

$=4*3.14*79^2\\=78386.96$ Square Yards$

Answer:

chisquare = 31.667

degree of freedom = 2

Step-by-step explanation:

Formula for chisquare test = (O-E)²/E

total number observations= 60 + 25 + 15 = 100

Estimated E,

80% x 100 = 80

15%x100 = 15

5% x 100 = 5

chisquare =

$\frac{(60-80)^{2} }{80} +\frac{(25-15)^{2} }{15}+\frac{(15-5)^{2} }{5}\\$

= 5 + 6.67 + 20

= 31.667

from the calculation above the value of the chisquare statistic = 31.67

the degree of freedom is the number of samples in the test n - 1

= 3-1

= 2

I have solve this question also in a tabular form to aid understanding in the file i uploaded.

thank you and good luck!
