According to a recent poll, 71% of adults who use the Internet have paid to download music. In a random sample of n = 750 adults who use the Internet, let p represent the proportion who have paid to download music. Complete parts a throughe below. a. Find the mean of the sampling distribution of p. Ep = 0.71 (Round to two decimal places as needed.) b. Find the standard deviation of the sampling distribution of p. GA = 0.0166 (Round to four decimal places as needed.) c. What does the Central Limit Theorem say about the shape of the sampling distribution of p? O A. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will approach the population distribution. O B. The Central Limit Theorem says that as the sample size grows large, the sampling distribution of p will become approximately normal. O C. The Central Limit Theorem does not say anything about the sampling distribution of p because it is not a population mean. O D. The Central Limit Theorem says that the shape of the sampling distribution of p is completely determined by the population parameter p. d. Compute the probability that p is less than 0.77. P(p<0.77) = (Round to three decimal places as needed.) e. Compute the probability that p is greater than 0.55. P(6>0.55) = (Round t three decimal places as needed.)

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
