You do 6x6 which is 36 and since there are 6 faces to a cube you do 36 x 6 and you get 216mm2
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
D. Is the false statement. Clearly, the rectangle was shifted and is no long in its same position
