Evaluate the following formula for p1−p2=0, p=0.140000, q=1−p, x1=69, x2=15, n1=316, n2=284, p1=x1n1, and p2=x2n2. z=p1−p2−p1−p2p•qn1+p•qn2

The Plush Zo store sells stuffed animals. The store is running a special on teddy bears this month. One day, the shopkeeper took a sample of stuffed animals at the store. She found that 4 of the 15 stuffed animals that she sampled were teddy bears. The store had 590 stuffed animals on that day, and 110 of those stuffed animals 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) V ? (b) Sample proportion: (Choose one) ▼

For this question, enter numbers using at most 3 decimal places, and use the rounded values for subsequent calculation if any intermediate values are rounded. For example, enter "0.2" for 1/5, but 0.333 for 1/3 (and if later you have 1/3 * 1/5, compute it as 0.2 * 0.333). There are two drawers in my desk, left one contains 4 blue pens and 6 red pens, and the right contains 1 blue pen and 4 red pens. What is the conditional probability of picking a blue pen given that I chose the left drawer? What is the probability of picking a blue pen if I first select a drawer uniformly at random, and then pick a random pen from that drawer? Finally, what is the probability of having picked a pen from the left drawer, given that I picked a blue pen? (don't forget to round to 3 decimal places).
In the first step of substituting the numbers into the formula, where is the 40 coming from in A= (1+0.08/40)4X38-1 / (0.08/4)
