CabockHow Do Honeybees Communicate Quality?When honeybees are looking for a new home, they send out scouts to explore options. When a scout returns, she does a "waggledance" with multiple circuit repetitions to tell the swarm about the option she found.¹ The bees then decide between the options andpick the best one. Scientists wanted to find out how honeybees decide which is the best option, so they took a swarm of honeybees toan island with only two possible options for new homes: one of very high honeybee quality and one of low quality. They then kept trackof the scouts who visited each option and counted the number of waggle dance circuits (HoneybeeCircuits) each scout bee did whendescribing the option.2 Comparative dotplots of number of circuits performed by the 41 bees that visited the high-quality option andthe 37 bees that visited the low-quality option are shown in the figure below.escA2optionN@2W88 800000000SClick here for the dataset associated with this question.Check out a honeybee waggle dance on YouTube!2Seeley, T., Honeybee Democracy, Princeton University Press, Princeton, NJ, 2010, p. 128.Xcommand#3erlookbooofa100CircuitsNumber of circuits completed in the honeybee waggle danceTED$0004C200TRF..de 40%5300VT6GMacBook ProY400B&7HU*8NJ1S(9KM*-0OCMViMu 5(d) The mean for the high-quality group is xH = 90.5 with a standard deviation of 94.6, while the mean for the low-quality groupis x = 30.0 with a standard deviation of 49.4.

A psychology lab doing research in dreams has 4 rooms (1,2,3, and 4), each containing 2 beds (A and B). Three pairs of twins are being studied tonight. Each pair of twins will be assigned to one of the four rooms, and then each twin will be assigned a specific bed in the room. How many ways are there to organize the experiment?

A computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting 8 workers at random and timing each worker on each assembly process. Half of the workers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, as shown in the table below. Worker 1 2 3 4 5 6 7 8 Process 1 64 65 32 76 76 90 75 71 Process 2 62 73 9 61 53 93 77 77 52 Difference 2 -8 23 15 23 (Process 1 - Process 2) 33 -3 -2 19 Send data to calculator Based on these data, can the company conclude, at the 0.05 level of significance, that the mean assembly times for the two processes differ? Answer this question by performing a hypothesis test regarding Hd (which is μ with a letter "d" subscript), the population mean difference in assembly times for the two processes.…

A sporting goods store announces a "Wheel of Savings" sale. Customers select the merchandise they want to purchase, then at the cash register they spin a wheel to determine the size of the discount they will receive. The wheel is divided into 12 regions, like a clock. Six of those regions are red, and award a 10% discount. The three white regions award a 20% discount and two blue regions a 40% discount. The remaining region is gold, and a customer whose lucky spin lands there gets a 100% discount - the merchandise is free! Determine each of the probabilities. Explain your answer. 10 a) What is the probability that a customer gets at least a 40% 10 100 discount? 40 10 10 20 20 10 10 | 40 20
A shoe company wants to test an updated model of a running shoe on its wear after one month of running. Which of the following describes a matched pairs design? They recruit 50 people who run on a regular basis to participate in their study. They will have the runners wear the shoes when they run for two months. After two O The subjects are numbered 1-50, and these numbers are put into a random number generator. The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the original model. months, the wear on the shoes will be determined using the depth of the tread and flexibility of the toe box. The wear between the new model and the original model will then be compared. The subjects' names are written on equal-sized slips of paper and placed into a hat. A researcher then reaches in and pulls out 25 slips of paper. These subjects are assigned to the new model group. The remaining 25 subjects will be…
A shoe company wants to determine if the new tread on its top line of running shoes lasts longer than the original tread. The company recruits 50 runners for a study. Each runner will perform their typical workout wearing one shoe with the original tread on one foot and another shoe with the new tread on the other foot. The foot that wears the new type of tread will be decided by flipping a coin. After one month, the runner will wear the new type of tread on the opposite foot. At the end of the second month, the difference in tread wear (New – Original) will be calculated. What type of sampling is described in this study? What is the appropriate inference procedure? one-sample t-test for one-sample z-test for p one-sample t-test for two-sample t-test for
250 adults are practicing every day before taking part in a high-stakes children's game. The game requires them carefully to remove a shape- either a star or an umbrella-from a sugar wafer. 30% of those who choose stars on a given day will switch to umbrellas the next day, and 20% of those who choose umbrellas on a given day will switch to stars the next day. (a) If 150 contestants practice with stars today, how many will practice with umbrellas tomorrow? (b) If the actual game is held a long time from now, what proportion of contestants do we expect will be practicing with stars each day close to then?
A person, Joe, claims to be able to "smell" an illness based on the odor of a person's clothing. Joe is given 12 shirts, each worn by a different person, some of whom had the illness and some of whom did not. The shirts were given to Joe in random order and he had to decide whether each shirt had been worn by an ill patient or by a healthy patient. joe identified 11 of the 12 shirts correctly. If we assume that Joe was just guessing, he would have probability 1/2 of correctly identifying each shirt. Find the probability that Joe would identify AT LEAST 11 shirts correctly by random guessing
