The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a standard deviation of 20¢. A study was done to test the claim that the mean cost of a daily newspaper is $1.00. Twelve costs yield a mean cost of 95¢ with a standard deviation of 18¢. Do the data support the claim at the 1% level?
Complete the blanks within the hypothesis testing procedures as follows:
Statements of null and alternative hypotheses:
H0: μ ___ $1.00
Ha: μ ___ $1.00
(where blanks 1 and 2 require appropriate symbol, such as “equal”, “not equal”, “less than” or “more than”)
Sample z score = (3 decimal places)
Critical z score(s) = (2 decimal places with indication of direction(s))
p-value = (4 decimal places)
Decision: null hypothesis (enter either “Reject” or “Do not reject”)

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
