6. You are constructing a 90% confidence interval for a sample consisting of n = 9 values and an
unknown population standard deviation. The population appears to be very skewed. Determine
whether a margin of error should be calculated using a critical value of za/2, a critical value of ta/2, or neither.
a) a critical value of za/2
b) a critical value of ta/2
c) neither
7. The standard deviation of sample size of n = 15 is 345 and the mean is 6784. Given that the population follows a normal distribution, construct a 90% confidence interval estimate of the mean of the population.
a) 6519
b) 6593
c) 6627
d)6783

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
