He randomly assigns 30 rats to one of three conditions, 10 rats to each condition. Group 1 gets buttered bread at the end of the maze, Group 2 gets cheddar cheese, and Group 3 gets honey-glazed ham. The number of seconds each rat took to run the maze is recorded. The hypothesis is that type of food makes a difference in rat running time.Choose the type of test you should use to test this hypothesis?Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).Z-testO single sample t-testdependent t-testindependent t-testPearson correlation t-testANOVAChi-Square Goodness of Fit TestO Chi-Square Test of IndependenceO Ho: µ1 - P2 = 0H1: P1 - P2 # 0O Ho: H1 - P2 <0

See picture for questions A and b Michael, a nurse manager at a local hospital, wanted to know more about the hospital's full-time nurses. He polled 12 nurses at random who work full-time at the hospital. The findings in the poll were that these nurses take, on average, 5.5. sick days per year, that 50% of them would prefer a four-day work schedule, and that 8 of them are married. Michael didn't know that the top hospital administrators had already surveyed all nurses who work full-time at the hospital. In that survey, it was found that the nurses take, on average, 5.7 sick days per year, that 61% of them would prefer a four-day work schedule, and that 77 of them are married.
Aidan is a goalie for his school’s hockey team. He normally stops 87% of the shots that come his way. In one particularly bad game, he let five of the 15 shots into the goal. He decides to cheer himself up by convincing himself that this game would be unusual for a goalie who stops 87% of the shots. He uses the table of random digits below using the rule that he will read across the row, two digits at a time, with 01–87 indicating a stop and 88–99 and 00 indicating a goal, until 15 attempts are recorded. 61373 70629 96541 81508 28214 06485 Which of the following statements about this random number table best describes the simulation?

Below are the first five letters of the alphabet, designed to fit the vertices of a grid. Below them in subparts (a) through (d) are the first four letters that were designed on other grids. Draw the "e" that goes with each type style, or font. As stated many times in this book, we want you to go beyond random trial and error. First, take some time and think. One strategy is to try to write the rules that the writer of the letter used. Another strategy is to try to articulate the common characteristics of the four letters.t abcde (a) (b) (c) تحاد EEEE abcd. BA م داد plo EEEE 0
Thomas makes five paper airplanes with different wing lengths. He drops them the same way from a height of two meters for five trials each. He records the amount of time it takes for each airplane to fall to the groupld. A. What is the independent variable? B. What is one control variable?
Thomas scored at the 45th percentile on the midterm. Which interpretation of his score is the best? Group of answer choices 45% of the people tested exceeded his score. Thomas had a better score than 45% of the people tested. Thomas got 45% of the items correct. More than one of the above is appropriate.
An instructor gave students the option to purchase an interactive program that allows them to answer questions during class and receive credit for participating. Alternatively, students could work an extra problem during weekly homework assignments. The instructor randomly selected 10 students, then randomly divided them into two groups of five each. One group was provided the interactive tool, the other group was asked to work the extra problem. The instructor knew from prior experience that the interactive tool increases attendance. The table below contains the final exam scores for the 10 students (on a scale from 0 to 100). Interactive: 65 78 84 88 96 Extra problem: 56 61 70 75 82 The instructor wishes to test whether increased attendance throughout the semester leads to improved exam scores. Let µ I = mean score that would be observed if all students used the interactive tool and µ E = mean score if all students worked an extra problem. The degrees of freedom, using a t table…
As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.
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…
Shenise is a star player for her women's basketball team. She has injured her ankle, and it is doubtful that she will be able to play in an upcoming game. If Shenise can play, the coach estimates that the team will score 91 points. If Shenise is not able to play, the coach estimates that they will score 70 points. The team doctor estimates that there is a 70% chance Shenise will play. Determine the number of points the team can expect to score.

If it was heads shc uscd namc-brand batteries and if it was tails she used the generic brand. She left the flashlights on and recorded how long it took for the batterics to wear out. The results showed that the flashlights that had the name-brand batteries, on average, lasted significantly longer than the flashlights that used the generic brand. What type of design is this study? a. This study is an example of a simple random sample. b. This study is an example of a matched pairs experiment. This study is an example of a completely randomized experiment. This study is an example of an obscrvational study. c. d.

[ Select ] Lorain wants to know if eating a small serving of dark chocolate before taking a test has any effect on the grade earned for that test. She randomly assigns students to either have 1 serving of dark chocolate or no chocolate before taking the same test. 3.
