- Part I: Sections 1.1 - 1.5 4. A flower garden has 40 flowers: 10 yellow, 5 white, 8 red, and 17 pink. Assume that 3 flowers are randomly selected. If the sampling is done with replacement, what is the (a) probability that the first two flowers are pink and the last flower is yellow? (b) probability that at least one of the flowers is red? If the sampling is done without replacement, what is theAn advertising agency wants to know whether the no of column inches of classified ad carried by 2 competing newspapers is equal. The no of column inches appearing in both newspapers, respectively, on 20 randomly selected days follows: 663 & 725, 713 & 806, 626 & 620, 682 & 626, 639 & 595, 651 & 614, 769 & 744, 701 & 719, 723 & 680, 670 & 639, 665 & 602, 639 & 657, 694 & 624, 614 & 614, 651 & 583, 632 & 682, 739 & 657, 657 & 639 & 775 & 745. Use signed-rank test at 0.01 level of sig to test to test whether or not newspaper 1 & 2 carry equal amount of classified ad. What is the z value and decision?Find the median, first quartile (Q1) and the third quartile (Q3) for the data shown, which is already sorted. The number of data is n= 11. Katye Kozak's algorithm: Sort the data and compute the median. When n is an odd number, the median is the center value. When n is an even number, the median is the center value. After computing the median, Q1 is the median of the 1st half of the data, not including the median value. Q3 is the median of the 2nd half of the data, not including the median value.

- The Infinite Monkey Theorem states that a monkey hitting keys completely at random on a typewriter for an infinite amount of time will, eventually, type any given text. Even the complete works of William Shakespeare. Some quotes are truly amazing. Consider the famous quote by Gen George S. Patton: "WHEN IN DOUBT, ATTACK" That's 21 amazing characters. Suppose a monkey is seated in front of a KEYBOARD WITH 28 CHARACTERS (one for each of the 26 letters in the alphabet, plus the space bar, and a comma). Suppose the monkey types only 21 characters completely at random. If X is the number of different 21 character strings it could have typed, then the chances that it typed the quote is one divided by X. What is X?

Let a₁ = 0.qrst, where q, r, s, and t are your numbers. Think of four more random integers u, v, w, and x, and add them to the end of a₁ to create a2 = 0.qrstuvwx. Repeat this process to generate a3, 94, and a5. If this process is continued infinitely many times, then explain whether or not the sequence {an} converges, diverges, or it is impossible to determine.An electronics store has received a shipment of 30 table radios that have connections for an iPod or iPhone. Twelve of these have two slots (so they can accommodate both devices), and the other eighteen have a single slot. Suppose that six of the 30 radios are randomly selected to be stored under a shelf where the radios are displayed, and the remaining ones are placed in a storeroom. Let X = the number among the radios stored under the display shelf that have two slots. (a) What kind of distribution does X have (name and values of all parameters)? binomial with n = 12, x = 6, and p = 6/12 binomial with n = 30, x = 12, and p = 6/30 hypergeometric with N = 30, M = 12, and n = 6 O hypergeometric with N = 12, M6, and n = 12 (b) Compute P(X = 2), P(X ≤ 2), and P(X ≥ 2).

- Please answer the second part (iv) (v) (vi) (vii)A group of Industrial Organizational psychologists wanted to test if giving a motivational speech at the end of a meeting would encourage office workers to have a higher output to their work based on the numbers of sales each workers made. The group tested 10 participants that were in two conditions where one meeting ended in a motivational speech and another were no motivational speech was given. Here are the number of sales that was produced by the 10 participants for both conditions: Yes speech: 2, 6, 1, 9, 3, 12, 8, 0, 5, 1No speech: 3, 0, 5, 10, 1, 8, 2, 1, 9, 11Use the four steps of hypothesis testing to find out if there is a significant difference between the two groups, using APA format to answer the question.
