- Which of the below-mentioned hypotheses is assumed to be true while we perform a hypothesis test?1. A factory manager needs to understand how many products are defective versus how many are produced. The number of expected defects is listed in Table A. A random sample was taken to determine the actual number of defects. This information is contained in Table B below. Table A Number produced 0-100 101-200 201-300 301-400 401-500 Number defective 5 6 7 8 10 Number produced 0-100 101-200 201-300 301-400 Table B 401-500 Number Defective 5 7 8 9 11Hello. Could anyone help me on this question? I have tried it four times and only one attempt left. What I am confusing is that some choice are not individual and variables. Like all young children, children who eat snack and cartoon characters. But if i leave them there, it shows me I am wrong. Pls help me on this and explanation would be appreciated. Thanks!
- According to a recent survey of first-year high school students, 28% chew gum daily. The students were also asked if they had recently gotten a cavity filled at the dentist. Of the 47% of first-year students who responded that they had a cavity recently filled, only 39% chewed gum daily. Is chewing gum independent of having a cavity filled recently? Yes, P(Gum) = P(Gum|Cavity). Yes, P(Gum) = P(Cavity|Gum). No, P(Gum) ≠ P(Gum|Cavity). No, P(Gum) ≠ P(Cavity|Gum).IN A SURVEY 106 STUDENTS REPORTED WETHER THEY LIKED THERE POTATOS MASHED, FRIED OR BAKED TWICE 57 LIKED THEM MASH, 35 LIKED FRENCH FRIES, AND 61 TWICE BAKED. IN ADDITION 21 LIKE BOTH MASHED AND FRIED POTATOS 11 LIKED FRENCH FRIES AND TWICE BAKED POTATOS, 22 LIKED MASHED AND BAKED, AND THREE LIKED ALL THREE, HOW MANY HATE POTATOS.

- Legal researchers were interested in learning whether a rape defendant's perceived guilt depends on the type of argument introduced by his defense attorney. Researchers classified each defense by whether or not it introduced the idea that the female victim was asking for the encounter—the “she shouldn't have worn that short skirt” defense. In a simulated juror situation, the researchers asked each of the 20 mock jurors to rate the guilt of the defendant on a scale from 1 to 7. This is a(n) _____ dependent variable, which means that the data can be analyzed using a _____ test. a. nominal; nonparametric b. ordinal; parametric c. ordinal; nonparametric d. nominal; parametricWhat is the equation for computing the degrees of freedom (df) for a hypothesis test of independence of categorical data? O df = (number of rows + 1) (number of columns + 1) df = (number of rows) (number of columns) df = (number of rows - 1) (number of columns - 1) O df = n - 1A psychologist wants to test the influence of color on object recognition in 4-year olds. She recruits 25 children and shows them two sets of pictures of everyday objects (variable = picture type), has the children name them, and measures the time it takes (variable = reaction time). She shows the children a color set of pictures first and then shows them a black and white set of pictures. a) What is the independent variable? b) What is the dependent variable? c) What is the second independent variable? d) What is the second dependent variable? e) Is "picture type" a within-subjects or between-subjects variable? f) What scale of measurement is reaction time? g) What scale of measurement is picture type? h) The order of presentation of the picture sets is what kind of variable?
- The University Secretary wants to determine how University grade point average,GPA (highest being 4.0) of a sample of students from the University depends on a student’s high school GPA (HS), age of a student (A), achievement test score (AS), average number of lectures skipped each week (S), gender of a student (where M=1 if a student is male or 0 otherwise), computer or PC ownership of a student (where PC=1 if a student owns a computer or 0 otherwise), the means of transport to school (drive, bicycle or walk; where D=1 if a student drives to campus or 0 otherwise, B=1 if a student bicycles to campus or 0 otherwise), and finally, the subject major of the student (finance, human resource, marketing and accounting; where F=1 if a student majors in finance or 0 otherwise, HR=1 if a student majors in human resource or 0 otherwise, MR=1 if a student majors in marketing or 0 otherwise). Use the correlation matrix and dummy regression output to answer the questions. GPA HS A AS…is there enough evidence to reject the claim?Suppose you roll 2 dice. What is the pobability that the sum of the 2 dice is exactly 4, given that the 1st dice is a 1?
