You are thinking of using a t procedure to construct a 95% confidence interval for the mean of a population. you suspect the distribution of the population is not normal and may be skewed. which of the following statements is correct? a. you should not use the t procedure because the population does not have a normal distribution. b. you may use the t procedure, provided your sample size is large, say at least 40. c. you may use the t procedure because it is robust to nonnormality.

26) -2(7x) = (-2 • 7) x a. associative property of addition b. associative property of multiplication c. commutative property of multiplication d. commutative property of addition

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
