An online news source reports that the proportion of smartphone owners who use a certain operating system is 0.216. Two simulati

ons will be conducted to create a sampling distribution of the sample proportion from a population with proportion 0.216. Simulation A will consist of 1,000 trials with a sample size of 50. Simulation B will consist of 500 trials with a sample size of 100. hich of the following describes the centers and variabilities that should be apparent in the distributions generated by simulation A and simulation B?
A. The centers will be approximately equal, and the variabilities will roughly be equal.

B. The centers will be approximately equal, and the variability of simulation A will be greater than the variability of simulation

C. The centers will be approximately equal, and the variability of simulation A will be less than the variability of simulation B.

D. The center of simulation A will be greater than the center of simulation B, and the variabilities will be approximately equal.

Nathan has some pencils. 3/4 of his pencils are yellow pencils. 2/3 of those lead pencils do not have erasers. What fraction of
Salsk061 [2.6K]

Answer:

The fraction of Nathan's pencils that are yellow without erasers is 1/2.

Step-by-step explanation:

The problem gave us two informations, the first one is the fraction of the total amount of pencils that Nathan has that are yellow, the second one is the fraction of those yellow pencils that don't have erasers. So in order to find the fraction of the total pencils that are yellow pencils without erasers we need to multiply the two fractions that were given to us. So we have:

yellow pencils without erasers = (3/4)*(2/3) = 6/12 = 1/2
