Jedi Master Astaal Vibum is interested in studying the midi-clorian count in younglings and how those levels change as they become padawan and ultimately full Jedi knights. To begin the study, Astaal randomly selected 43 younglings and measured their midi-clorian counts. Measurements will be taken annually until they leave the Jedi order or reach the level of Jedi Master. What is the population of this study? Question 1 options: 1) All Jedi younglings 2) All Jedi knights 3) The 43 younglings measured 4) All children
Chapter 4, Section 2, Exercise 065 Finger Tapping and CaffeineThe effects of caffeine on the body have been extensively studied. In one experiment1, researchers examined whether caffeine increases the rate at which people are able to tap their fingers. Twenty students were randomly divided into two groups of 10 students each, with one group receiving caffeinated coffee and one group receiving decaffeinated coffee. The study was double-blind, and after a 2-hour period, each student was tested to measure finger tapping rate (taps per minute). The goal of the experiment was to determine whether caffeine produces an increase in the average tap rate. The finger-tapping rates measured in this experiment are stored in CaffeineTaps. A distribution of differences in means, x¯c-x¯n, for randomization samples from this experiment is given in the figure below.Let group 1 be the people who have had coffee with caffeine and let group 2 be the people who have had coffee without caffeine.…
Researchers investigated two kinds of laugh tracks – one with posed laughter and one with spontaneous laughter. Recall that to create the posed laughter laugh track, the researchers asked people to laugh and recorded the results. The researchers also tested the same 40 jokes with a spontaneous laughing laugh track, which they created by having people watch funny videos and recording their laughter. The data can be found in the file LaughTypes in pictures. Put these data into the Matched Pairs applet to investigate whether the type of laughter makes a difference in the ratings of the jokes and also do parts (a) (b) and (c):

With a terrain and make of concrete, experience from national highways suggests that there are, on the average, 2 potholes per mile after a certain amount of usage. We wish to know how likely it is to find no more than one pothole in a section of 5 miles of a highway. What is the average number of potholes in a section of 5 miles of a certain highway?
A student wondered what proportion of a large jar of thousands of marbles were red and speculated that it was 0.30. She took a random sample of 50 marbles and got 18 red marbles, for a sample proportion of 0.36. Below is a dotplot of 100 simulated samples of drawing 50 marbles from a population that is set up to have the proportion of "red marbles" to be 0.30. Based on this dotplot, would getting a sample of 50 marbles to have a 0.36 proportion of red marbles be significant evidence that the true proportion of red marbles in the whole jar is greater than 0.30?
A health researcher studying child birth is interested in the possible effect that smoking by the mother during pregnancy has on the baby's birth weight. To investigate, the researcher conducts an observational study by reviewing 400 records of women in their twenties who have recently given birth for the first time. For each record, he notes whether or not the woman smoked during pregnancy and the baby's birth weight, in addition to the woman's education level, and age. From the data, the researcher creates two groups: women in their twenties who smoked during pregnancy and women in their twenties who did not smoke during pregnancy. Then he compares the average birth weight between the two groups. (a)Why might the researcher have chosen to perform an observational study (by gathering information from past records) and not a randomized experiment (by assigning pregnant women to either the smoking or nonsmoking group at random)? Choose the best answer from the choices below. In a…

During the current quarantine, a certain ISE statistics professor has been playing video games on an Xbox with his 11-year-old son. The dad never wins. However, often during a match the kid goes out of his way to not just beat his dad, but to humiliate him. After several games, the dad collected data on the number of times his son humilates him in a single match: in 43% of the matches, the son humilates the dad 4 times; 24% of the time, the dad is humilated 3 times; 18% of the time, he is humilated twice; 15% of the time he is humilated only once; and there are no matches in which the dad was not humilated by the son. Compute the variance of the number of times the dad is humilated by his son. (four decimal places)
