Answer:
the probability that the average diameter of those sand dollars is more than 4.73 centimeters is 0.5910
Step-by-step explanation:
Given information:
mean, x = 5
standard deviation, σ = 0.9
number of sample, n = 16
now we calculate the probability that the average diameter of those sand dollars is more than 4.73 centimeters.
P(x>4.73) = P (z > (4.73 - x) / (σ 
)
= P (z > (4.73 - 4) / (0.9 
)
= P (z > 0.203)
= 0.5910

is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing to
we get a= 3 , b= 5 and c = 7
Now we have to find
adding and subtracting 2uv in numerator we get
Substituting the values from (i) and (ii) we get
Hence, the value of 
is
Yes, this question is statistical because the temperature in North Carolina is a number based of temp which makes it a statistical number.
