The Plush Zoo store sells stuffed animals. The store is running a special on teddy bears this month. On a certain day, 2 out of every 11 stuffed animals in the store were teddy bears. That day, the shopkeeper took a sample of stuffed animals in the store. She found that 20 of the 59 stuffed animals that she sampled were teddy bears. For the shopkeeper's sample, find and write with proper notation the population proportion and sample proportion of stuffed animals that were teddy bears. Write the proportions as decimals (not percentages) rounded to two decimal places. (a) Population proportion: (Choose one) = 0 X 5 ? (b) Sample proportion: (Choose one) = 0For a large, top-rated corporation, 96% of employees said the corporation is a great place to work. Suppose that we will take a random sample of $ employees. Let p represent the proportion of employees from the sample who said the corporation is a great place to work. Consider the sampling distribution of the sample proportion p. Complete the following. Carry your intermediate computations to four or more decimal places. Write your answers with two decimal places, rounding if needed. (a) Find HA (the mean of the sampling distribution of the sample proportion). HA = X 5 ? (b) Find GA (the standard deviation of the sampling distribution of the sample proportion). GA = X
