Suppose the researchers had been able to randomize 1,000 persons (randomly selected from the same
population of persons with migraine headaches) to receive Acupuncture treatments. Suppose a histogram is a
made of individual headache severity scores (three months post-randomization) for these 1,000 individuals. Cot
Which of the following likely describes this histogram?
The
The histograrn will look approximately like a normal distribution because the sample size is large so the Central
Limit Theorem applies.
nu
he histogram will look like a t-distribution with 999 degrees of freedom.
8
The histogram will appear to be right (positively) skewed, with similar mean and standard deviation as the sample D
of n=173.
h
The histogram will appear to be right skewed with a similar mean as the sample of n=173, but with standard
deviation equal to (16 divided by the square root of 1.000).

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle
